I’m a machinist by trade. I’ve been able to transfer that knowledge to building my own parts. Watching Ian and his detail break down of firearms has taught me enough to be able to design my own from scratch and rebuild complicated parts kits. I still don’t make triggers etc . I just use them from other guns etc .
Watercooling is infact used and very common on naval guns, even today. Most 76 and even 127mm guns use this. They are naturally mounted to the boat so you dont have the issue with mobility.
Jacob Lester I've read that the Italian guns don't mind salt water, but they need to be flushed with fresh water once they've finished firing. I presume it's similar with other systems. MrAnton275 I'm glad you commented on naval guns using water-cooling. I was gonna do comment on it myself if I didn't spot yours first!
As a retired manufacturing engineer from the auto industry current the current manufacturing process is to do concurrent design, tooling, machining and quality development which speeds up the process considerably and gives you a better quality product in the end. The old style of manufacturing would be to release the design, have a hand made prototype made and then tell manufacturing to make it. This led to many problems as the design would not lend itself to mass production and or would not be economical to make due to tooling costs. With all the modifications made to the product in the end it was usually a bunch of compromises and the complete process would normally take around 4 years to complete to production. Nowadays completely new models make it to production in about two years with the original design more or less intact because you have design engineers working hand in hand with manufacturing, quality & production before the design is completed.
I was at the Springfield Armory museum a few weeks ago, and they had a display showing all the operations and machine tools it took, just to manufacture the rear peep sight for an M1 Garand. They actually started as a steel pipe which was cut into thin slices, machined, and then separated into multiple pieces for finishing work.
I assume that Gun Jesus can make lots of things transform into different things, but water into oil or something sounds like it could possibly be the most common option.
we in the uk get to use lee enfeilds in the cadets some are converted to .22lr but we got to use full bore .303 when on camp and some even got to use the sa80 im lefthanded so i got to use an enfeild it was so cool
Holy hell, someone else is wants a Koborov TKB-022M! Honestly, a general Eastern European tour would be great in general, just because of some of the weird post-war, Soviet era designs that proliferated or got mass-produced but never really found a place outside the area, like the Czechoslovakian ZB-47 with it's almost-inline magazine, or the Danuvia helical feed designs out of Hungary. I do think the existing Koborov prototypes are in the Tula Arms Museum, which is connected heavily to the KBP Tula arms factory and I suspect that the elements of the Koborov design ended up being used in the A-91M, ADS, and the OC-69, particularly the forward ejection mechanism or inspired it.
As old as this video is, i'm sure someone has already commented (you may even have addressed in a later video i haven't seen yet) - but there is one more con to an open-bolt machinegun: runaway. Most (if not all? certainly all I have handled) open-bolt guns fire as soon as the bolt is in battery - the firing pin is fixed or floating in such a position that it "interferes" with the space the primer occupies when the bolt is closed. The means that if your trigger sear is worn, damaged, or (M240/M249 - falls off because the trigger group lock pin is worn out), the gun will begin firing and not stop until it is starved of ammo. I actually saw this happen in BCT on the MG range - M-249 had been incorrectly reassembled by the recruit lugging it and the trigger/grip assembly was not properly seated. Bolt locked open just fine by hand, but as soon as he started firing it, it vibrated out of position and wouldn't stop firing. Fortunately, the drill sergeant supervising was paying attention, and stomped on the belt to break it and it ended up only sending about 10-15 undesired shots downrange. Of course, 10-15 undesired shots is fine going down range. much less okay if you're walking on patrol and your LBV bumps into the takedown pin enough to push it out...
Howwww? The M249's pin (at least) is like an inch and a half long. The front goes probably 180° around the pin it hangs on. How could that be worn? Also you just grab the charging handle and hold it until you can flip the top cover open and toss the belt out. That's definitely trained and drilled for the M249 because you haven't typically got an AG.
Just to touch on your bit of machining vs firearm making you are absolutely correct. If you learn the trades of running a mill, lathe, welder, etc., you will be well suited for getting into gunsmithing/manufacturing. I grew up doing primarily automotive based machining and just within the past 3 years or so got into gunsmithing and really there wasn't any transition outside of instead of machining crankshafts and fitting heads to blocks it's machining receivers and threading barrels.
Found it funny 14 Q&A's in you still have to answer "What is the difference between an open bolt and a closed bolt gun". These people haven't watched enough of your videos, but proud they support your channel regardless. Keep it up man!
I'm with you on the M14. Ironic isn't it that the US would adopt such a rifle that wasn't properly developed, yet they threw out the AR-10 because they thought it wasn't properly developed. Guess it helped that the M14 had "Springfield" written on it. I wonder, was it that the rifles weren't properly developed, or was it the concept of the select-fire battle rifle itself that wasn't developed yet?
Quick comment on the water cooling. We are still using water to cool in rapid fire naval guns, also some anti aircraft cannon such as ZSU-23-4 have water jacket around the barrels.
Grief, Having a little time off, and watching old videos from forgotten weapons, and it always impresses me how well thought out, and knowledgeable Ian is in the realm of manufacturing. Manufacturing is all I do, and I collect old "obsolete" manufacturing machines, and he really understands just how CNC has actually effected manufacturing, not a lot of people get it even in the field, it is not magic! It and better cutting tools (carbide, cubic boron nitrade), make less setups, and interruptions, and this is mostly prominent visible in mass production. As to accuracy, he gets it, yes the CNC makes getting good accuracy better, faster, but its not a requirement, all the bits and bobs in the CNC that allows the kind of precision and accuracy seen can be bolted on to any machine tool! Of course, as a collector of old machining stuff, and a manufacturer. I want a decent CNC metal shaper, and overarm horizontal mill. Those tools allow for shapes that are almost impossible to do (cost effectively) on modern equipment! Only edm's, and expensive custom rotary brooches can make some of the shapes shapers make, and those both move slow, and take a lot of power for that slow movement. P.S. thats why some designs just dont get made anymore, for any reason. If the parts have to be metal, and have things like blind square holes, or extreme straight contours, they often dont get made, cnc is not up to the task of those shapes.
lol I think everyone knows that the MP5 is still a very viable platform. However I think he just wanted you to talk about the MP5 just to hear your thoughts on it. Which I'm all for! 😁
I'm kind of surprised the Liberator wasn't on that list of uncomfortable firearms. I remember seeing Karl jump around a bit after a few shots with that thing.
Just to be technical, the bolt of a G3 should stop on the buffer in the stock. The bolt can also max out the buffer, and then it will stop on the stock directly. Sweden has been using extended buffers in their AK4s to fix this. The spring is never fully compressed.
Was thinking more in the line of Hugh Hefner, but with guns instead of woman. But now I can't stop thinking about a wizard packing a Garand and 1911. 🤔 "You shall not PASS!" *BANG BANG BANG BANG BANG BANG BANG BANG PING*
This is brilliant. I hope he sees this and uses it for his next themed match. Gundalf the wise, with such great wizardy, he can make a 30-06 Chauchat fire every time!
With regards to manufacturing, at the end of the day, cutting metal is cutting metal. And yes, aerospace does require a high degree of precision on a lot of things. Some of my parts have holes with a tolerance of .0006".
I'm just gonna apologize in advance for being an arrogant jerk here, but honestly. Six thou is not really impressive at all in terms of precision. I "grew up" in medical equipment, and I've had tolerances of 4/1000 mm. To be honest, I thought tolerances on firearms would be tighter than automotive, but makes sense that they're not really. I mean, for an engine to work you'd need things to fit. And I'd have to disagree on the cutting metal is all the same too, actually. Massive difference between say alu and duplex in terms of almost everything related to the cutting. Maybe not to the layman, tho.
Look again. I said 6 tenths, not thou. And at the end of the day, cutting aluminum is cutting aluminum. Cutting titanium is cutting titanium. There might be differences in what the machines are capable of, but the principals are the same.
On the obsoleteness of mp5/sugmachine guns in general. We had mp5s as the only handheld weapons on board our coast guard vessel when I was serving in the Norwegian coast guard. Norway has adopted hk416 variants in all roles the mp5 used to be used, except for a few mp7s (a pdw) here and there. The guys on my ship, still fought tooth and nail to keep the "obsolete" mp5. A coast guard in peacetime Norway generally do not need weapons. We have them, for the few occasions we do need it, but we almost never do. You don't bring a gun aboard a civilian fishing or cargo vessel since it is rude, increases tension and we have a cannon if shit hits the fan. As such we do not want to devote training time and money to upgrade our firearms to short hk416s. We would never use them anyway. Secondly, a submachine gun is awesome on board a ship. You don't need the penetrative force of 556. And certainly not the excessive penetration commonly seen in PDWs like mp7. We do not want to risk hitting friendlies or equipment through interior walls. We want the round to stop in anything if we miss. 9mm does that. Mp5 is also a very easy weapon to use. We can field personell with decent enough shooting, even as they almost never train with the platform. Not that 416 is difficult, but few things are as easy to shoot full auto than mp5. Basically, mp5 is still a beloved gun in the hands of those that still has it. That means rear echelon guys that do not want to use the gun, but still need to have one.
The only advantage over a long-barrel AR-15 is the compact size, and lack of blast(9mm from a long 9 inch barrel is not too bad). That's it. If that's enough, then I'd also rather keep the MP5.
Fair enough but not necessarily just that though, I mean.. It would be quite difficult to make a 5.56mm NATO round not go through walls if you were in a scenario where you didn't want to shoot through walls or something for example. If that example wasn't a problem in an operation in a building - an 5.56mm SBR AR would be better than an MP5 mostly.
The 9mm actually has more penetration than the 5.56 and adding a shorter barrel to a 5.56 will reduce it's velocity by quite a bit, thus giving even less chance of OP to the 5.56. An SBR in 5.56 is about as handy as an MP5. The 5.56 has a range advantage over the 9mm. The only advantage the 9mm has is less report, especially if the 5.56 is an SBR. The smg is looking to be obsolescent. Not upgrading for the sake of upgrading has been proven to put militaries behind their enemies when war breaks out. My Grandfather escaped the Nazis during their occupation of Norway and served in the Norwegian Navy aboard a US ship named the Trailblazer. I want to visit someday and meet my relatives.
For millitary surplus stuff most countries have a few really good items. I just pick and choose what is best. I like a lot of the Scandinavian stuff because it's really high quality and great for cold weather. German stuff from the 80's is super good and cheap. Yugo stuff is good and Bulgarian Soviet and Soviet stuff is also pretty good if you can get over the simplicity of some of the stuff. My favourite price at the moment is my British officers greatcoat from ww2 but it needs some repairs other then that my Finnish Hungarian helmet is great and my Swedish tunic and Mauser Swedish bandolier is also really cool.
AS an Avid Follower of you Videos, and someone who runs Nerf Events for Underprivilaged Children, I love that you where not dismissive of Nerf, Keep up the good work Sir.
Hi, Ian beside to Patreon I decided to send you a proper wine cup, from Chile. Is not “acceptable” you to drink fine wine in a cup like this. When you use the glass in a video I may send you a fine wine bottle.
Alvaro Bravo Bravo sir, I was tempted to do the same with a whiskey glass but as you are from the American land mass and it would be appropriate for some Item from there.
Part of the reason you see very few open bolt semi-auto designs on the commercial market is that the ATF classified open-bolt designs as machine guns under US law. Even semi-auto open bolt guns are considered machine guns because the ATF assumes they are readily convertable to full auto. Not every open bolt design is actually readily convertable but that's how the law is being enforced.
One application where water cooling may make a return, is with remote weapon stations/unmanned turrets on future armoured vehicles. With modern tanks or armoured vehicles, the crew still has access to the firearm to change the barrels when they get hot, and, they frequently do from reports I have read. With the current movement towards more unmanned turrets, the needs of heat management for the MG may need to be looked and re-evaluated.
About double-barreled repeating pistols; I've done some very speculative calculations on futuristic ammunition. Suppose that you had a cartridge firing extremely light bullets at extremely high speed, using little propellant(if any). These qualities should make for a higher ratio of muzzle energy to total recoil impulse, so firing two of these at once could be manageable enough even if it's a very powerful cartridge by ~2000 pistol standards. And armor-piercing capability is only going to become more important. But it would probably require a pretty long barrel compared to the caliber to reach these high velocities; If you wanted to use a scaled-up version of the cartridge, it may become too long for a pistol, even if the materials you're using allow it to be light enough. And besides, any difficulties with mechanical complexity should be reduced as manufacturing technology improves, and should also be reduced if cartridges become smaller.
Russia? Perhaps, you should contact Max Popenker the author of "Modern Firearms" website and several books on guns. He speaks English, besides for a year or two he works for "Kalashnikov Concern". However Korobov worked in a different factory - Tula, not Izhevsk.
Ian, next time you're in the UK it would be worth contacting BASC. They have a few excellent examples of punt guns as well as Bill Harriman of Antiques Roadshow fame on staff and I think a collaboration video on punt guns between you two would be awesome.
in response to your 'water cooled barrel' question...in Naval operations there is the OTTO MOLERA 76 mm that is water cooled, they even make a 'super rapide' version that is 180 rpm artillery that is definitely water cooled
With regards to surplus kit - British CS95 kit is fantastic, comfortable, practical, hard-wearing, all the stuff you want. The lightweight trousers are the most comfortable I've ever worn. I've got a soft spot for Soviet and East German stuff too, not as pretty or as comfy, but very sturdy and the Soviet cold weather kit is impossible to beat for warmth. Can't comment so much on LBE as I've not managed to pick any up yet (I've got most of a P37 webbing set). I do have an East German assault pack and a Soviet sidor, both are a bit clumsy and outdated but actually surprisingly good, practical little backpacks that are impossible to break.
wine! plastic cup! i! am! uncomfortable! guns which have some sort of springloaded mechanism are a pain in the ass to disassamble. nothing's more frustrating than flying gunparts.
1:05:00 The best version of the carcano being the Type I that uses a true 6.5 bore diameter, uses Mauser style stripper clips, and a Mauser style magazine, and is chambered for 6.5 Japanese. A type I in a short 18"-20" barrel carbine configuration would be a very nice handy, effective rifle right up there with the K98k Mauser rifles and their clones.
You ought to have mentioned that while yes, firearms designing is often just a game of trade-offs there are certainly design choices that provide benefit with no negatives.
From one that actually studied metal restauration and conservation at s master level. Usually you are better with good conservation. at least from a historic value pov.
I thought the PKM was the best GPMG until I used it. It's still very good, but _'best'_ depends on how you're expecting to use it. I still really like the PKM.
My understanding is that most of the design time for a firearm is figuring out how to get the tooling set up and get the rifles made, and then adapting the initial design to realized manufacturing.
I had a mossberg 500 persuader for all of 3 months and one outing to the range, like Ian I was left with a sore hand for a few days, and I understood why I was able to buy it for $85.
Regarding the recoil Thing (first question): I believe the HK G36 is a prime example where recoil was minimized to be almost non-existent. I am pretty sure that the bolt carrier receives just enough energy to cycle without slamming all the way back. The gun is fairly light and I've tried Shooting both the M16 and the M4 who both kicked like a mule compared to the 36.
Good description of how machining has changed in the last 50 years. CNC machines have condensed 20, 30, 40 operations- one per machine and operator- to 3 or 4. Parts are also much more consistent because they are only handled 2 or 3 times. One of the main goals when planning a part is how to reduce the number of times it has to be handled to the minimum. They can also be checked faster and more precisely. 50 years ago there would be a set of go/no-go gauges at every operation. They all had to be made by hand along with the fixturing and any special cutters. You couldn't justify all that unless you were going to make thousands of whatever the product was. Now you can make a couple hundred of something for a reasonable price because nearly all that special one-of-a-kind tooling is eliminated.
Regarding punt guns: A video that I would love to see would be starting with something like a .410 shot gun and big paper targets at different ranges, and slowly work your way up to a punt gun. Bonus points if you do the firing from a dock or something over water, and bring the punt gun in on an actual punt.
Still at least two punt guns in operation in the south east of Ireland. Huge area of swamp/estuary down there full of duck. They don't use them for waterfowling anymore, but to keep the (probably grandfathered) licenses they have to fire them at least once a year. Notoriously dangerous. Dozens of stories of guys shooting other guys in the twilight, failures due to bad loading, all kinds of accidents.
Yep, I want my Nerf blasters to be as tacticool as possible! That involves both cramming the rails with the latest accessories and using blasters that employ cool features of forgotten weapons.
The Chinese Type 81 assault rifle, which looks like an AK but isn't, was designed to be more controllable and accurate in automatic fire than the type 56, which IS an AK. This is indeed achieved by giving bolt and bolt carrier further to travel with a better-balanced spring force. But everything is in more or less the same place as on the type 56, so reservists can adapt to it without being retrained from scratch. (The type 03 rifle seems to be an alternative to the type 95, which fires the same ammunition, but has the same layout as the type 81, again so that reservists don't need extensive retraining.) In actual fact, the magazine well on the type 81 is slightly further forward than on the type 56, which is how the bolt gets more room to travel. The type 81's action is supposed to have been developed from the SKS, but I'm not confident that's the whole story.
To be fair, they also did develop the 7.62 Nato, which is by far the best thing to come out of that program. They also improved the gas system on the M1, whether these things should have taken 12 years to do, probably not.
By the way of those question about the difference between to make guns and to make other metal stuff. In the beginning of the invasion of Germans into Soviet Russia Stalin's regime lost around 80% of the guns factories localized mostly in Kharkov. So! The new, very simplistic model of PPSz 41 (PPS 42) was as simple as it could be. And most of those machine guns were made by factories in Moscow. For example - by a factory where to this time they produced metal beds.
Blade Runner 2049 was incredible. The visuals were so beautiful that they'd take your breath away - glad to see that Roger Deakins finally got the Oscar he deserved decades ago. Damn shame that the film didn't do well at the box office, and damn shame that it didn't even get nominated for best film.
You probably won't even see this and you may have already though about it but Larry Vickers has some pretty solid contacts in Russia. I realize he has a huge production company backing him up but perhaps they could help you gain access to some of those collections.
I like the PGO Mossberg, because I can buy it, put in for my SBS stamp, and while I'm waiting to stock it I can cut it for chokes, pattern it to determine the best load, and when I get my stamp back the hard part is already done. Kind of like an AR pistol for me, I can get the timing and gas system working with the short barrel, instead of waiting until the stamp comes back.
toomanyaccounts clearly you don't know what quicker means. Buy a PGO shotgun and take it (with it's 14" barrel) home today, or *pay for* a premade SBS that I *cannot take possession of* until my stamp comes back. Take home today, wait for stamp. Take home today, wait for stamp. Which fucking option is fucking quicker, you vulgar moron? P.S. moron, quicker 'than', not quicker 'then'. You can't be an effective (notice I didn't put affective) asshole *and* be wrong.
toomanyaccounts (technical note first, the quality of the guns will be the same regardless, I can attach a vertical grip to a 'firearm', which is what a weapon is called that would be a shotgun except it was never manufactured with a butt-stock, and fuck those stupid magazine kits. I'm buying a tube fed gun for the advantages of a tube fed) clearly I've failed to effectively communicate this with you. if I buy the PGO, non-NFA firearm, I can take it home the day I buy it, and while my stamp is coming back to put a stock on it I can cut the barrel for chokes, shoot and pattern it, and have a functional shotgun. If I buy a premade SBS I *CANNOT* possess it/take it home/remove it from the dealer who is holding it. So while my stamp is coming back, I *CANNOT* cut it for chokes, pattern it, or use it in any way, shape, or form. Is that clear enough? Or is this just a waste of time because you cannot possibly conceive of a distinction between "paying for" and "possessing"?
15:28 One in particular I am aware of is WalcomS7, He created the "Paradym Shift" which has a feed system similar to a 1917 Burton LMR, the concept of which he got from your video on the firearm
10:48 look up sig's updated facility in NH. That's your quality assurance engineer. By measuring each manufactured part, and the machine it's manufactured with, any time you receive a firearm that's not functioning properly, you can hone in on those data and determine exactly what parameters need to be adjusted -- both on the part and the tooling.
I think you're forgetting MIM (metal injection molding) otherwise known as powder metallurgy. Powder metallurgy is almost like 3d printing in the idea that you add material and you can make shapes and complicated parts that wouldn't be practical by milling and do it for less cost because you're not wasting shaved material. Powder metallurgy has now gotten to the point where even tool steels can be made with MIM and the quality of MIM parts can far exceed the quality of forged or cast parts. MIM has severely reduced the cost of complex parts when compared to milling so complex or more intricate parts can be produced practically.
I think Ian was trying to speak from his own knowledge, instead of just regurgitating generalities about what techniques currently exist. Also: MIM is not considered acceptable yet for gun parts, since the parts are seen as inferior to forged and milled. They are seen as equivalent to castings.
Not Pulverman You should probably learn about MIM or how manufacturing works at all before you start regurgitating shit. If a guy who doesn't know about metallurgy tells you about metallurgy, that just makes you a guy who also doesn't know about metallurgy and then that makes the people who read your comment more people who also don't know about metallurgy :P A lot of gun parts are actually made by MIM and it just isn't labeled as such because no one really cares what process unless it's the receiver generally speaking. MIM is actually used disproportionately more than other steels in blade steels. Blade steels are generally considered one of the most demanding areas for modern metallurgy. If you know a decent amount about knives, you've heard of S30v which is the creme de la creme of knife steels valued because it's ultra hard and tough but not overly brittle, that's powder metallurgy. Disregarding that, you don't need the creme de la creme of modern metallurgy, mild steel does perfectly fine in 99% of applications and forged parts consequently use generally the lowest grade of metal they can find for gun parts because it doesn't matter. Porosity and grain size was a problem in the late 1900's that's way way way gone, now the surface finish of MIM exceeds the surface finish of forged even at the cheapest level of MIM manufacturing. The only reason why MIM isn't used for pretty much everything in the firearms industry is because consumer perception and scale of manufacture. MIM is better suited to large production. Firearm owners, who don't know anything about manufacturing, don't understand that there's such a thing as high quality MIM with near perfect surface finish and tool steel hardness and excellent toughness with brittleness on par with other tool steels of the same hardness at very much reduced cost. Because the firearms industry is very consumerist, people's opinion and marketing matter more than almost anything else.
Not Pulverman The only and sole reason why milling exists in modern firearm manufacture is because people are stupid enough to buy it. Billet steel can be stronger in tool steels where the maximum tensile strength is greater than the maximum tensile strength a forged part can achieve HOWEVER there isn't a single part in an ar 15 that's a tool steel. The only part that is somewhat hardened is the bolt and only case hardened. Billet parts have absolutely no advantage and are insanely expensive for it. The only reason it's still alive is because of consumer perception. The gun industry in the civilian market is completely supported by marketing and consumer opinion.
Re punt guns, I have fired one when I was a youngster. The one I used wasn't cartridge but a bag of powder with shot or even scrap. Gun itself was just lashed down with rope, I did hear of someone who used nylon rope which stretched and the gun smashed his face. You lie flat on your stomach in the punt and have a short paddle in either hand to propel yourself. Idea was to sneak up on a large flock of birds while they were still on the water and "let fly". You then moved in with the 12 bore to finish off any wounded or stragglers. Not for the faint hearted.
I had a feeling you were going to say Carcano. I quite like the ones I have had, since it is a part time safe queen and shot from a bench I quite like it's quirks.

Watercooling is infact used and very common on naval guns, even today. Most 76 and even 127mm guns use this.
They are naturally mounted to the boat so you dont have the issue with mobility.
Nor an issue with finding water.
Well there is a sea of it, quite literally.
It would interesting to know if they use salt water or not because of corrosion
+Jacob Lester
as for russian systems - they use sea water
Jacob Lester
I've read that the Italian guns don't mind salt water, but they need to be flushed with fresh water once they've finished firing. I presume it's similar with other systems.

I'm glad you commented on naval guns using water-cooling. I was gonna do comment on it myself if I didn't spot yours first!
As a retired manufacturing engineer from the auto industry current the current manufacturing process is to do concurrent design, tooling, machining and quality development which speeds up the process considerably and gives you a better quality product in the end. The old style of manufacturing would be to release the design, have a hand made prototype made and then tell manufacturing to make it.

With all the modifications made to the product in the end it was usually a bunch of compromises and the complete process would normally take around 4 years to complete to production. Nowadays completely new models make it to production in about two years with the original design more or less intact because you have design engineers working hand in hand with manufacturing, quality & production before the design is completed.
Cool comment, kid.
I was at the Springfield Armory museum a few weeks ago, and they had a display showing all the operations and machine tools it took, just to manufacture the rear peep sight for an M1 Garand. They actually started as a steel pipe which was cut into thin slices, machined, and then separated into multiple pieces for finishing work.
drinking wine in a plastic cup.

Honestly, a general Eastern European tour would be great in general, just because of some of the weird post-war, Soviet era designs that proliferated or got mass-produced but never really found a place outside the area, like the Czechoslovakian ZB-47 with it's almost-inline magazine, or the Danuvia helical feed designs out of Hungary. I do think the existing Koborov prototypes are in the Tula Arms Museum, which is connected heavily to the KBP Tula arms factory and I suspect that the elements of the Koborov design ended up being used in the A-91M, ADS, and the OC-69, particularly the forward ejection mechanism or inspired it.
we need to see them do a 2 gun match with nerf guns as a joke.
you ever seen airsoft 3 gun its odd
As old as this video is, i'm sure someone has already commented (you may even have addressed in a later video i haven't seen yet) - but there is one more con to an open-bolt machinegun: runaway. Most (if not all? certainly all I have handled) open-bolt guns fire as soon as the bolt is in battery - the firing pin is fixed or floating in such a position that it "interferes" with the space the primer occupies when the bolt is closed. The means that if your trigger sear is worn, damaged, or (M240/M249 - falls off because the trigger group lock pin is worn out), the gun will begin firing and not stop until it is starved of ammo.
I actually saw this happen in BCT on the MG range - M-249 had been incorrectly reassembled by the recruit lugging it and the trigger/grip assembly was not properly seated. Bolt locked open just fine by hand, but as soon as he started firing it, it vibrated out of position and wouldn't stop firing. Fortunately, the drill sergeant supervising was paying attention, and stomped on the belt to break it and it ended up only sending about 10-15 undesired shots downrange.
Of course, 10-15 undesired shots is fine going down range. much less okay if you're walking on patrol and your LBV bumps into the takedown pin enough to push it out...
Howwww? The M249's pin (at least) is like an inch and a half long. The front goes probably 180° around the pin it hangs on. How could that be worn? Also you just grab the charging handle and hold it until you can flip the top cover open and toss the belt out. That's definitely trained and drilled for the M249 because you haven't typically got an AG.
Just to touch on your bit of machining vs firearm making you are absolutely correct. If you learn the trades of running a mill, lathe, welder, etc., you will be well suited for getting into gunsmithing/manufacturing. I grew up doing primarily automotive based machining and just within the past 3 years or so got into gunsmithing and really there wasn't any transition outside of instead of machining crankshafts and fitting heads to blocks it's machining receivers and threading barrels.
Found it funny 14 Q&A's in you still have to answer "What is the difference between an open bolt and a closed bolt gun".
These people haven't watched enough of your videos, but proud they support your channel regardless. Keep it up man!
I'm with you on the M14. Ironic isn't it that the US would adopt such a rifle that wasn't properly developed, yet they threw out the AR-10 because they thought it wasn't properly developed. Guess it helped that the M14 had "Springfield" written on it.
I wonder, was it that the rifles weren't properly developed, or was it the concept of the select-fire battle rifle itself that wasn't developed yet?
It look twelve years to make!
And the Italians did it better.
TheGoldenCaulk maybe the m14 was half in the bag ?
Does that mean in a sense, the M-14 is like the F-35 lighting 2?
Honestly if they had taken the Italian approach with the BM-59 the idea would’ve lasted a lot longer.
Quick comment on the water cooling.
We are still using water to cool in rapid fire naval guns, also some anti aircraft cannon such as ZSU-23-4 have water jacket around the barrels.
Grief, Having a little time off, and watching old videos from forgotten weapons, and it always impresses me how well thought out, and knowledgeable Ian is in the realm of manufacturing.
Manufacturing is all I do, and I collect old "obsolete" manufacturing machines, and he really understands just how CNC has actually effected manufacturing, not a lot of people get it even in the field, it is not magic! It and better cutting tools (carbide, cubic boron nitrade), make less setups, and interruptions, and this is mostly prominent visible in mass production.
As to accuracy, he gets it, yes the CNC makes getting good accuracy better, faster, but its not a requirement, all the bits and bobs in the CNC that allows the kind of precision and accuracy seen can be bolted on to any machine tool!
Of course, as a collector of old machining stuff, and a manufacturer.
I want a decent CNC metal shaper, and overarm horizontal mill. Those tools allow for shapes that are almost impossible to do (cost effectively) on modern equipment! Only edm's, and expensive custom rotary brooches can make some of the shapes shapers make, and those both move slow, and take a lot of power for that slow movement.
P.S. thats why some designs just dont get made anymore, for any reason. If the parts have to be metal, and have things like blind square holes, or extreme straight contours, they often dont get made, cnc is not up to the task of those shapes.
"Well... a plastic up of decent wine." A thumbs up for you sir. Good show.
lol I think everyone knows that the MP5 is still a very viable platform. However I think he just wanted you to talk about the MP5 just to hear your thoughts on it. Which I'm all for! 😁
It's fairly mediocre.
I'd say it gets most of its "viability" from being so mass produced, that it's very available.
@@notpulverman9660 always gotta be someone around to spout a contrarian opinion even if it doesn't really have any basis in facts of any kind, huh
I totally agree with the M14. Not thinking of it as we conceptualize it nowadays, but just back then - yeah. Totally agree.
No, Ian has a lot of intelligent incites. It is refreshing to hear someone that is articulate about firearms.
Insights....duh
I'm kind of surprised the Liberator wasn't on that list of uncomfortable firearms. I remember seeing Karl jump around a bit after a few shots with that thing.
maybe because it didn't see any real world use
Just to be technical, the bolt of a G3 should stop on the buffer in the stock. The bolt can also max out the buffer, and then it will stop on the stock directly. Sweden has been using extended buffers in their AK4s to fix this. The spring is never fully compressed.
1:02:00. There are gun farms!? Where can i find one?
In the UK they are entirely banned, as it is not known if handgun seeds will accidentally land and subsequently grow on them.
"I'm a lead farmer M0%#3R F@#%3r!"
Texas
It's super to have timed questions in description, easy to navigate and get info you need, big thanks!
Having a glass of wine while watching Ian have a glass of wine. This is how I spend my Saturday evenings these days.
I'm not complaining.
The lubricated VS fluted chamber question is genius. Bravo.
Please.. For love of what's holy, please please please film the next Q&A in front of a fireplace while smoking a pipe!!
+Thomas Christensen so a *'Gundalf'* setting you mean then Tom ?
Was thinking more in the line of Hugh Hefner, but with guns instead of woman.
But now I can't stop thinking about a wizard packing a Garand and 1911. 🤔
"You shall not PASS!"
*BANG BANG BANG BANG BANG BANG BANG BANG PING*
This is brilliant. I hope he sees this and uses it for his next themed match. Gundalf the wise, with such great wizardy, he can make a 30-06 Chauchat fire every time!
I'm really happy that you got to shoot the colt CMG machine gun being a literal "unicorn" that I really did not expect you to be able to shoot.
With regards to manufacturing, at the end of the day, cutting metal is cutting metal. And yes, aerospace does require a high degree of precision on a lot of things. Some of my parts have holes with a tolerance of .0006".
I'm just gonna apologize in advance for being an arrogant jerk here, but honestly. Six thou is not really impressive at all in terms of precision. I "grew up" in medical equipment, and I've had tolerances of 4/1000 mm. To be honest, I thought tolerances on firearms would be tighter than automotive, but makes sense that they're not really. I mean, for an engine to work you'd need things to fit. And I'd have to disagree on the cutting metal is all the same too, actually. Massive difference between say alu and duplex in terms of almost everything related to the cutting. Maybe not to the layman, tho.
Look again. I said 6 tenths, not thou. And at the end of the day, cutting aluminum is cutting aluminum. Cutting titanium is cutting titanium. There might be differences in what the machines are capable of, but the principals are the same.
Holy shit, InRange and FW Q&As back to back? Is there a such thing as too much content?
No.
TheGoldenCaulk let's not forget the nice long video with Bloke otR
It took 12 years to make.
The only problem I have is trying to find time to watch all these videos :-(
TheGoldenCaulk I did not read the hidden part yet. So,
No!
When I read the whole thing. No.
Keep up the fun posts, man.
On the obsoleteness of mp5/sugmachine guns in general. We had mp5s as the only handheld weapons on board our coast guard vessel when I was serving in the Norwegian coast guard. Norway has adopted hk416 variants in all roles the mp5 used to be used, except for a few mp7s (a pdw) here and there. The guys on my ship, still fought tooth and nail to keep the "obsolete" mp5.
A coast guard in peacetime Norway generally do not need weapons. We have them, for the few occasions we do need it, but we almost never do. You don't bring a gun aboard a civilian fishing or cargo vessel since it is rude, increases tension and we have a cannon if shit hits the fan. As such we do not want to devote training time and money to upgrade our firearms to short hk416s. We would never use them anyway.
Secondly, a submachine gun is awesome on board a ship. You don't need the penetrative force of 556. And certainly not the excessive penetration commonly seen in PDWs like mp7. We do not want to risk hitting friendlies or equipment through interior walls. We want the round to stop in anything if we miss. 9mm does that.
Mp5 is also a very easy weapon to use. We can field personell with decent enough shooting, even as they almost never train with the platform. Not that 416 is difficult, but few things are as easy to shoot full auto than mp5.
Basically, mp5 is still a beloved gun in the hands of those that still has it. That means rear echelon guys that do not want to use the gun, but still need to have one.
Taeerom exactly, and I also think that submachine guns have some purposes still.
The only advantage over a long-barrel AR-15 is the compact size, and lack of blast(9mm from a long 9 inch barrel is not too bad).
That's it. If that's enough, then I'd also rather keep the MP5.
Fair enough but not necessarily just that though, I mean.. It would be quite difficult to make a 5.56mm NATO round not go through walls if you were in a scenario where you didn't want to shoot through walls or something for example. If that example wasn't a problem in an operation in a building - an 5.56mm SBR AR would be better than an MP5 mostly.
What about 9mm AR carbines?
The 9mm actually has more penetration than the 5.56 and adding a shorter barrel to a 5.56 will reduce it's velocity by quite a bit, thus giving even less chance of OP to the 5.56. An SBR in 5.56 is about as handy as an MP5. The 5.56 has a range advantage over the 9mm. The only advantage the 9mm has is less report, especially if the 5.56 is an SBR. The smg is looking to be obsolescent. Not upgrading for the sake of upgrading has been proven to put militaries behind their enemies when war breaks out.
My Grandfather escaped the Nazis during their occupation of Norway and served in the Norwegian Navy aboard a US ship named the Trailblazer. I want to visit someday and meet my relatives.
For millitary surplus stuff most countries have a few really good items. I just pick and choose what is best. I like a lot of the Scandinavian stuff because it's really high quality and great for cold weather. German stuff from the 80's is super good and cheap. Yugo stuff is good and Bulgarian Soviet and Soviet stuff is also pretty good if you can get over the simplicity of some of the stuff. My favourite price at the moment is my British officers greatcoat from ww2 but it needs some repairs other then that my Finnish Hungarian helmet is great and my Swedish tunic and Mauser Swedish bandolier is also really cool.
AS an Avid Follower of you Videos, and someone who runs Nerf Events for Underprivilaged Children, I love that you where not dismissive of Nerf, Keep up the good work Sir.
Thanks for answering my question on my birthday of all days.
Hi, Ian beside to Patreon I decided to send you a proper wine cup, from Chile. Is not “acceptable” you to drink fine wine in a cup like this. When you use the glass in a video I may send you a fine wine bottle.
Alvaro Bravo Bravo sir, I was tempted to do the same with a whiskey glass but as you are from the American land mass and it would be appropriate for some Item from there.
Carcano rifles have had absolutely mind blowing performances...too soon?
A thought on the fluting question; one other factor for consideration would be the case strength in regards to the bottom and rim.
Part of the reason you see very few open bolt semi-auto designs on the commercial market is that the ATF classified open-bolt designs as machine guns under US law. Even semi-auto open bolt guns are considered machine guns because the ATF assumes they are readily convertable to full auto. Not every open bolt design is actually readily convertable but that's how the law is being enforced.
One application where water cooling may make a return, is with remote weapon stations/unmanned turrets on future armoured vehicles. With modern tanks or armoured vehicles, the crew still has access to the firearm to change the barrels when they get hot, and, they frequently do from reports I have read.
With the current movement towards more unmanned turrets, the needs of heat management for the MG may need to be looked and re-evaluated.
About double-barreled repeating pistols; I've done some very speculative calculations on futuristic ammunition. Suppose that you had a cartridge firing extremely light bullets at extremely high speed, using little propellant(if any). These qualities should make for a higher ratio of muzzle energy to total recoil impulse, so firing two of these at once could be manageable enough even if it's a very powerful cartridge by ~2000 pistol standards. And armor-piercing capability is only going to become more important. But it would probably require a pretty long barrel compared to the caliber to reach these high velocities; If you wanted to use a scaled-up version of the cartridge, it may become too long for a pistol, even if the materials you're using allow it to be light enough. And besides, any difficulties with mechanical complexity should be reduced as manufacturing technology improves, and should also be reduced if cartridges become smaller.
Russia?
Perhaps, you should contact Max Popenker the author of "Modern Firearms" website and several books on guns. He speaks English, besides for a year or two he works for "Kalashnikov Concern". However Korobov worked in a different factory - Tula, not Izhevsk.
You were right!
Ian, next time you're in the UK it would be worth contacting BASC. They have a few excellent examples of punt guns as well as Bill Harriman of Antiques Roadshow fame on staff and I think a collaboration video on punt guns between you two would be awesome.
in response to your 'water cooled barrel' question...in Naval operations there is the OTTO MOLERA 76 mm that is water cooled, they even make a 'super rapide' version that is 180 rpm artillery that is definitely water cooled
I've only made it this far back cause I use your QnA videos to fall asleep too.
You should narrate audio-books my guy.
With regards to surplus kit - British CS95 kit is fantastic, comfortable, practical, hard-wearing, all the stuff you want. The lightweight trousers are the most comfortable I've ever worn. I've got a soft spot for Soviet and East German stuff too, not as pretty or as comfy, but very sturdy and the Soviet cold weather kit is impossible to beat for warmth. Can't comment so much on LBE as I've not managed to pick any up yet (I've got most of a P37 webbing set). I do have an East German assault pack and a Soviet sidor, both are a bit clumsy and outdated but actually surprisingly good, practical little backpacks that are impossible to break.
wine! plastic cup! i! am! uncomfortable!
guns which have some sort of springloaded mechanism are a pain in the ass to disassamble. nothing's more frustrating than flying gunparts.
Always happy to see a q&a
1:05:00 The best version of the carcano being the Type I that uses a true 6.5 bore diameter, uses Mauser style stripper clips, and a Mauser style magazine, and is chambered for 6.5 Japanese. A type I in a short 18"-20" barrel carbine configuration would be a very nice handy, effective rifle right up there with the K98k Mauser rifles and their clones.
The machine tools at FN sound like horizontal mills, not shapers. Shapers use a linear motion kind of like a plane but on metal.
Nnnnnnnnnnnnnnneeeeeeeeeeeeeeeeerrrrrrrrrrrrrrrddddddd
You ought to have mentioned that while yes, firearms designing is often just a game of trade-offs there are certainly design choices that provide benefit with no negatives.
From one that actually studied metal restauration and conservation at s master level. Usually you are better with good conservation. at least from a historic value pov.
I thought the PKM was the best GPMG until I used it. It's still very good, but _'best'_ depends on how you're expecting to use it. I still really like the PKM.
Yes, do redo those interesting yet formerly forgotten weapons.
And as always Thanx Ian.
My understanding is that most of the design time for a firearm is figuring out how to get the tooling set up and get the rifles made, and then adapting the initial design to realized manufacturing.
Fun Fact: That bottle of wine was originally a wine bottle full of water, but before he started filming he did his thing.
I had a mossberg 500 persuader for all of 3 months and one outing to the range, like Ian I was left with a sore hand for a few days, and I understood why I was able to buy it for $85.
Ross Rifle Restorations out of Canada reproduces stocks, barrel bands and nose caps. They do really cool work!
I had a farm-raised gun. Great shooter, never missed a gopher.
Keep up the amazing content man. I play these videos like podcasts at work.
I carried a Mag-58 in Afghan, and will never speak poorly about it.
Regarding the recoil Thing (first question): I believe the HK G36 is a prime example where recoil was minimized to be almost non-existent. I am pretty sure that the bolt carrier receives just enough energy to cycle without slamming all the way back. The gun is fairly light and I've tried Shooting both the M16 and the M4 who both kicked like a mule compared to the 36.
Good description of how machining has changed in the last 50 years. CNC machines have condensed 20, 30, 40 operations- one per machine and operator- to 3 or 4. Parts are also much more consistent because they are only handled 2 or 3 times. One of the main goals when planning a part is how to reduce the number of times it has to be handled to the minimum. They can also be checked faster and more precisely. 50 years ago there would be a set of go/no-go gauges at every operation. They all had to be made by hand along with the fixturing and any special cutters. You couldn't justify all that unless you were going to make thousands of whatever the product was. Now you can make a couple hundred of something for a reasonable price because nearly all that special one-of-a-kind tooling is eliminated.
I love how you listed every topic in the description !
Regarding punt guns: A video that I would love to see would be starting with something like a .410 shot gun and big paper targets at different ranges, and slowly work your way up to a punt gun. Bonus points if you do the firing from a dock or something over water, and bring the punt gun in on an actual punt.
Still at least two punt guns in operation in the south east of Ireland. Huge area of swamp/estuary down there full of duck. They don't use them for waterfowling anymore, but to keep the (probably grandfathered) licenses they have to fire them at least once a year. Notoriously dangerous. Dozens of stories of guys shooting other guys in the twilight, failures due to bad loading, all kinds of accidents.
I used to drink beer as I watch Ian's vids...switched to wine last week, and hey this one comes next!
Nice. Edible gun facts with no attempt to baffle with bs.
"Green side out, Brown side out, run in circles, scream and shout." Old Marine saying caused by that haversack. A Blanket roll would have been better.
Yep, I want my Nerf blasters to be as tacticool as possible! That involves both cramming the rails with the latest accessories and using blasters that employ cool features of forgotten weapons.
The Chinese Type 81 assault rifle, which looks like an AK but isn't, was designed to be more controllable and accurate in automatic fire than the type 56, which IS an AK. This is indeed achieved by giving bolt and bolt carrier further to travel with a better-balanced spring force. But everything is in more or less the same place as on the type 56, so reservists can adapt to it without being retrained from scratch. (The type 03 rifle seems to be an alternative to the type 95, which fires the same ammunition, but has the same layout as the type 81, again so that reservists don't need extensive retraining.)
In actual fact, the magazine well on the type 81 is slightly further forward than on the type 56, which is how the bolt gets more room to travel. The type 81's action is supposed to have been developed from the SKS, but I'm not confident that's the whole story.
nerf stands for non expanding reuseable foam dunno why i know that but now you all do too
To be fair, they also did develop the 7.62 Nato, which is by far the best thing to come out of that program. They also improved the gas system on the M1, whether these things should have taken 12 years to do, probably not.
About the question of differences between firearms manufacturing and other stuff - Polish FB Radom also made sewing machines.
This is the most relaxing thing.
By the way of those question about the difference between to make guns and to make other metal stuff. In the beginning of the invasion of Germans into Soviet Russia Stalin's regime lost around 80% of the guns factories localized mostly in Kharkov. So! The new, very simplistic model of PPSz 41 (PPS 42) was as simple as it could be. And most of those machine guns were made by factories in Moscow. For example - by a factory where to this time they produced metal beds.
An example of weird nerf gun ideas is Walcom s7’s works, like the paradigm shift
Blade Runner 2049 was incredible. The visuals were so beautiful that they'd take your breath away - glad to see that Roger Deakins finally got the Oscar he deserved decades ago. Damn shame that the film didn't do well at the box office, and damn shame that it didn't even get nominated for best film.
The M14 and her variants are some of my all time favorite guns, but yeah I'd have to agree with you Ian.
Thanks for answering my question. Cheers!
(I might even consider finding myself a Carcano now!)
good set of questions!
Is this the FW version of the Great War channel Chair of Wisdom? The chair looks like a german tunic with the red piping.
You probably won't even see this and you may have already though about it but Larry Vickers has some pretty solid contacts in Russia. I realize he has a huge production company backing him up but perhaps they could help you gain access to some of those collections.
I like the PGO Mossberg, because I can buy it, put in for my SBS stamp, and while I'm waiting to stock it I can cut it for chokes, pattern it to determine the best load, and when I get my stamp back the hard part is already done. Kind of like an AR pistol for me, I can get the timing and gas system working with the short barrel, instead of waiting until the stamp comes back.
toomanyaccounts clearly you don't know what quicker means. Buy a PGO shotgun and take it (with it's 14" barrel) home today, or *pay for* a premade SBS that I *cannot take possession of* until my stamp comes back.
Take home today, wait for stamp. Take home today, wait for stamp. Which fucking option is fucking quicker, you vulgar moron?
P.S. moron, quicker 'than', not quicker 'then'. You can't be an effective (notice I didn't put affective) asshole *and* be wrong.
toomanyaccounts (technical note first, the quality of the guns will be the same regardless, I can attach a vertical grip to a 'firearm', which is what a weapon is called that would be a shotgun except it was never manufactured with a butt-stock, and fuck those stupid magazine kits. I'm buying a tube fed gun for the advantages of a tube fed) clearly I've failed to effectively communicate this with you.
if I buy the PGO, non-NFA firearm, I can take it home the day I buy it, and while my stamp is coming back to put a stock on it I can cut the barrel for chokes, shoot and pattern it, and have a functional shotgun.
If I buy a premade SBS I *CANNOT* possess it/take it home/remove it from the dealer who is holding it. So while my stamp is coming back, I *CANNOT* cut it for chokes, pattern it, or use it in any way, shape, or form.
Is that clear enough? Or is this just a waste of time because you cannot possibly conceive of a distinction between "paying for" and "possessing"?
Regarding the artillery part of the water cooling question, this system is widely used in naval artillery, specialy russian. AK-630 is a good example.
Im sure Bloke on the Range can also attest to the M1 cartridge belt's ease of use, being able to reload his Garand in ~4 seconds
15:28 One in particular I am aware of is WalcomS7, He created the "Paradym Shift" which has a feed system similar to a 1917 Burton LMR, the concept of which he got from your video on the firearm
Hey Ian, you should ask Larry Vickers about his connections to view stuff in Russia. Might be a good start.
10:48 look up sig's updated facility in NH. That's your quality assurance engineer.
By measuring each manufactured part, and the machine it's manufactured with, any time you receive a firearm that's not functioning properly, you can hone in on those data and determine exactly what parameters need to be adjusted -- both on the part and the tooling.
I think you're forgetting MIM (metal injection molding) otherwise known as powder metallurgy.
Powder metallurgy is almost like 3d printing in the idea that you add material and you can make shapes and complicated parts that wouldn't be practical by milling and do it for less cost because you're not wasting shaved material. Powder metallurgy has now gotten to the point where even tool steels can be made with MIM and the quality of MIM parts can far exceed the quality of forged or cast parts. MIM has severely reduced the cost of complex parts when compared to milling so complex or more intricate parts can be produced practically.
Nice! That's a cool idea.
I think Ian was trying to speak from his own knowledge, instead of just regurgitating generalities about what techniques currently exist.
Also: MIM is not considered acceptable yet for gun parts, since the parts are seen as inferior to forged and milled.
They are seen as equivalent to castings.
Mim is seen as inferior because it's cheaper, yet the cheapness doesn't get passed onto the consumer in any significant way.
Not Pulverman You should probably learn about MIM or how manufacturing works at all before you start regurgitating shit. If a guy who doesn't know about metallurgy tells you about metallurgy, that just makes you a guy who also doesn't know about metallurgy and then that makes the people who read your comment more people who also don't know about metallurgy :P
A lot of gun parts are actually made by MIM and it just isn't labeled as such because no one really cares what process unless it's the receiver generally speaking. MIM is actually used disproportionately more than other steels in blade steels. Blade steels are generally considered one of the most demanding areas for modern metallurgy. If you know a decent amount about knives, you've heard of S30v which is the creme de la creme of knife steels valued because it's ultra hard and tough but not overly brittle, that's powder metallurgy.
Disregarding that, you don't need the creme de la creme of modern metallurgy, mild steel does perfectly fine in 99% of applications and forged parts consequently use generally the lowest grade of metal they can find for gun parts because it doesn't matter. Porosity and grain size was a problem in the late 1900's that's way way way gone, now the surface finish of MIM exceeds the surface finish of forged even at the cheapest level of MIM manufacturing.
The only reason why MIM isn't used for pretty much everything in the firearms industry is because consumer perception and scale of manufacture. MIM is better suited to large production. Firearm owners, who don't know anything about manufacturing, don't understand that there's such a thing as high quality MIM with near perfect surface finish and tool steel hardness and excellent toughness with brittleness on par with other tool steels of the same hardness at very much reduced cost. Because the firearms industry is very consumerist, people's opinion and marketing matter more than almost anything else.
Not Pulverman The only and sole reason why milling exists in modern firearm manufacture is because people are stupid enough to buy it. Billet steel can be stronger in tool steels where the maximum tensile strength is greater than the maximum tensile strength a forged part can achieve HOWEVER there isn't a single part in an ar 15 that's a tool steel. The only part that is somewhat hardened is the bolt and only case hardened. Billet parts have absolutely no advantage and are insanely expensive for it. The only reason it's still alive is because of consumer perception. The gun industry in the civilian market is completely supported by marketing and consumer opinion.
your knowledge astounds me.
If you ask me Ian, I agree with your opinion on the M14.
Re punt guns, I have fired one when I was a youngster. The one I used wasn't cartridge but a bag of powder with shot or even scrap. Gun itself was just lashed down with rope, I did hear of someone who used nylon rope which stretched and the gun smashed his face. You lie flat on your stomach in the punt and have a short paddle in either hand to propel yourself. Idea was to sneak up on a large flock of birds while they were still on the water and "let fly". You then moved in with the 12 bore to finish off any wounded or stragglers. Not for the faint hearted.
I would love to see you do a forgotten weapons episode on a nerf gun. Would be a great april 1st episode
I had a feeling you were going to say Carcano. I quite like the ones I have had, since it is a part time safe queen and shot from a bench I quite like it's quirks.
Thanks to you, Ian, Chinese mystery pistols are now expensive.
