As a mechanical engineering student this is awesome to see the manufacturing process and prototyping, as a gun enthusiast it is just as awesome. Hope to start my own gun company one day and you are a major role model. Keep up the fantastic work.

Tell me you’re an engineer without telling me you’re an engineer Serbu: I’m using spokes in a 50 cal hand guard to prevent spooky sounds to buy a jet eventually
Thank you for going in to detail about the extrusion prosses. As soon as you said "maybe they could extrude the holes in" my mind went at 100mph for a couple minds before I worked out how it must be done. I was pretty damn close to what you said haha.
@@JD-hy6yc I think just the opposite. There will be little demand except novelty. That guy and his channel have a main demographic of 15 year old gamers. Not a big part of the gun buying community really.
@@joshuagibson2520 you cant even buy an ak from his company. literally all for show. i mean i love the ak guys channel but no chance of actually getting a product from him.
That's a really nice piece, and I have to believe it's going to save a crap-ton in production costs over the older guard. Really cool having the M-Lok on there. God knows there's plenty of debate on what's the bestest EVAR system for attaching crap, kinda like everything else in the world of firearms, but I've been really happy with M-lok so far.
Well done !!! Upon a side note... Anytime I am looking for a new tool, I always in due time, type a few series's of words, that further define the tool I am looking for. For example, You showcased the thread rolling machine. Well, when typing in that word(s) "thread rolling machine", it is often times, the search results will show every blasted manufacturer of the industrial world who makes the "thread rolling machines"... SO, what I do, is I soon after that acquiring the base line of what is offered from the industrial word, I type various words in front of the "thread rolling machine" like, "PORTABLE".... or "HAND HELD", SMALL, BENCH TOP, etc.... of course, these are descriptive words, as stated to further define the search engine to hone in on what I want... The reason I mention this is, I have found some really amazing tools, that way, that I would have otherwise, NEVER found, as the search engine will only point in one direction, to get me answers. I then follow that batch of words with additional descriptive words, like DIY, HOME MADE, SCRATCH BUILT.. granted, that often time will not showcase units for sale, or not offered in a production run, but, beings I have no issue making my own tools, when none are offered, you can pretty much count on some other idiot like myself, that spent 900 hours R&D'ing a one off machine, to perform a job once that only took 1.3 seconds to do, and I can harvest his/her ideas to make the choice if I need to justify making one too?... There is my two none cents...
We did our little threaded parts like that in a little 3 jaw lathe and a homeade die holder in the tailstock . That little threading device is pretty cool
I was wondering ho you were going to thread music wire, I was suspecting a thread rolling operation but when you broke out the table top model of thread roller I was in gadget nirvana, lol. A couple of things you probably have thought about but I will mention anyway just in case are maybe consider adding a small counterbore to the trunnion so the spokes find their location easier. Another may be to use a pressed powdered metal part for the end cap so it’s net shape and you don’t have to slice it and machine it. The pressed part could also have the step down and smaller bore to maintain the alignment with the barrel with less material overall required than an extrusion and an extra piece? Your videos just make me feel like I’m part of your team and want to help-even if you don’t want or need it 😬 Keep up the good work!
@Tony Bjorklund Thanks for the comments! Powdered metal would be a good choice for the end flange but I don't think we'll ever have the quantities to make it cost effective. There is already a small counterbore in the threaded holes in the trunnion. I'm sure the plastic spoke guide/damper will be what we end up using and should do very well.
Not sure what is different but the quality of your video is outstanding. I know this takes a lot of time and money, thanks for your videos I have learned a lot.
Very nicely done, especially the double bird! I have always loved rolled threads. When I comment on them most people say, "What?" It is almost unbelievable the amount of work/thought that you put into your projects. Yes, I did get the alert for this video. Thanks Mark. I also hope(pie in the sky hope) that the NFA is somehow done away with so you are flooded with orders.
Mark, as usual you are being creative and always thinking about how to improve the quality of your rifles! I hate that TH-cam has become such a pain and taking away monetization. Either way, keep up the great work and I hope to one day be able to even see one of your rifles in person.

I would make the front piece spoke retainer from laser cut aluminum plate, then a quick clean up on the cnc mill. Might be cheaper then a custom aluminum extrusion die and minimum order of material.....
I love these kinds of videos: because of my interest in gunsmithing. It's real neat to see the use of bicycle spokes in that handguard and that it is tuned to G# which makes me think of a bass, cello, and violin. Any chance we will hear a filtered audio sample of the prototype being fired in a future video? If so, thanks in advance.
One day soon I will have enough saved up to order one, and so it's nice to see the upgrades. Never get notifications of your videos. Think you pissed off TH-cam, good for you, bad for your videos.
Will you be revamping the BFG50A entirely or just making some improvements, a totally extruded and milled 50A would look killer. Always hyped for new videos and updates on all your genius and dastardly plans
Very fucking cool! Would a gasket of NavCom be what is used as the dampener? It's already used for a few products for guns as well as industrial matting for under machine tools to reduce or stop operational vibration . Increasing life of said tool from it not dealing with harmonics as much. It CAN also tighten the precision realized on older tools.
I think the extrusions are pretty good. I still think spokes are a bit odd, while it has not been done before(???). Any way, as long as they dont rust it should be good. Great that it saves time! Extrusions seem to be the way to go for handguards on guns today. Looking at the other/old handguard, i think you can make that part from just one sheet of metal, so you only have to weld one seam. Also the holes can be punched in one go for the M-Lock. If you think what you have got is better, go for it. Aluminum is lighter, and does not corrode. The extrusion I suspect will be a bit more precise, but who knows maybe a stamped part front guard can be accurate when it is welded in a rig made for it. I think that is fast too. Good luck with the build! Greetings, Jeff
Mark, what about reducing the OD of the trunnion, and just sliding the extrusion over it? Drill / tap the trunnion and poof bobs your uncle! (Like AR barrel nut meeting a handguard}
I think I could make those spokes from my hospital bed in my room. If you need someone to do it. I have a vast machine shop career and gunsmithing. Mostly shotguns for competition trap skeet sporting clays. But being bed bound has stopped my life. But im willing to help you Mark.
So this isn't an April fool's joke? Lol i thought this was all a joke until i looked at the last video. Some times it's hard to tell with you hahaha. That's crazy I'd never would have thought that handguard would hold 6k lbs. Very creative man.
What about the carbon fiber bicycle spokes ? Oz =lbs= pain ??? Is there a break down in the plans ??? E: Interupted threads but access to a locking nut ??? 2 cam tabs 1 ether side ? What's the effective accuracy like now ?
Imma call it the wind chime. So damn cool mark! May I ask what steel you make the spokes out of? 1085? Glad you went over the extrusion process, I was very curious as to how it was done. Amazing how pliable the aluminum can become.
I work at a place that does aluminum extrusions..I keep telling my boss we need to talk to the firearm industry more. they tell me they have, but I think they're just saying that.
I was stuck at the Tampa airport for 10 hours the other day, it would of been cool to stop bye and check out your shop instead of waiting for Southwest Airlines to fix their screw up haha
Thank you for not making the handguard out of space age polymer(plastic) or some chinesium pot metal It's nice that someone still gives a sh-t about quality and builds things to last.
I have a question; Where do you find quality 50 BMG brass. I built a 50 BMG benchrest rifle that shoots 1/3 moa with Lapua brass. Then they quit selling Lapua brass. So I rebarreled to 375CT and had a new bolt made. So your AR style 50s are intriguing I would like to buy one if I could solve the brass problem.
I'm intrigued by the "spoke" system within the guard and the purpose for it. I watched the other video where you shortly explained about the tensile strength of wire and properties of steel under tension, but I must admit I don't understand how this interacts or effects the weapon and its operation. Is there a "problem" you were looking to solve (Like numb hands from excess vibration) that required a creative solution like this ? As far as I knew with the original form of the handguard and the way it was welded, I thought was purely from a practical standpoint of just making a part fit. I didn't think the handguard had any additional function to the actual operation of the weapon. Which is why I don't seem to understand the purpose of the spoke system. I mean this with the utmost respect because I love creative mechanical engineering solutions, but what problem does it solve ?
I can take a guess. How do you hold the handguard on to the rest of the weapon without it coming loose or deforming? As near as I can tell, the whole tuning thing is the equivalent of using a torque wrench. This allows for a piece that by itself is too weak in shear to easily be extruded and fitted. So, the major advantage is in manufacturing. Another benefit isn't weight savings, but the thickness allows attachments to work. Making the steel that thick would have made everything too heavy. However, welding aluminum is apparently pretty difficult.
Is the primary reason for this pretensioned system to have a certain strength to weight ratio? I generally get the impression that people don't mind a lot of extra weight on that style of firearm, but lights certainly appeals to me.
Certain object in tension are always stronger than under compression. Suspension bridges are good examples of the idea. Plus getting a .50 BMG to be lighter is always a bonus.
So with these spokes keeping the harmonics in tune, would it be feasible to adjust them and dial in any accuracy issues? Sorry if it's a dumb question lol
I am REALLY curious as to how that behaves under the load of a cartridge firing and what it sounds like (and what it sounds/behaves like when one wire is under less or more tension, because let's face it, that IS going to happen in the field eventually).
In the interest of simplicity as well as damage tolerance, have you considered attaching the guard to the trunnion by way of a heavy force fit? Once in place they can be pinned or screwed to the trunnion to ensure it does not back out due to vibration from firing.
Once established, extrusion is usually more cost effective at higher production volumes than machining from each one from billet. Not an engineering reason, but yeah....
I doubt it's so much an engineering reason as it is a speed and price reason. Still shouldn't be any less capable of handling the stresses though. Edit: 7:00 LOL as soon as I finished typing this he says exactly that. Go figure.

I can take a guess. How do you hold the handguard on to the rest of the weapon without it coming loose or deforming? As near as I can tell, the whole tuning thing is the equivalent of using a torque wrench. This allows for a piece that by itself is too weak in shear to easily be extruded and fitted. So, the major advantage is in manufacturing.
Another benefit isn't weight savings, but the thickness allows attachments to work. Making the steel that thick would have made everything too heavy. However, welding aluminum is apparently pretty difficult.
My finger has come in contact with a cutoff wheel or two in my day. Probably a complaint by people who aren't hand tool friendly.
hi mark - what is the purpose of using the spokes under high tension instead of just screwing the AL extrusion mlok rail into the machined trunnion?
when will the 50a be ready for sale again?
Is the primary reason for this pretensioned system to have a certain strength to weight ratio? I generally get the impression that people don't mind a lot of extra weight on that style of firearm, but lights certainly appeals to me.
Certain object in tension are always stronger than under compression.
Suspension bridges are good examples of the idea.
Plus getting a .50 BMG to be lighter is always a bonus.
So with these spokes keeping the harmonics in tune, would it be feasible to adjust them and dial in any accuracy issues? Sorry if it's a dumb question lol
Thanks for the video. So could people potentially order and install a different handguard if they wanted to change up there rifle?
I am REALLY curious as to how that behaves under the load of a cartridge firing and what it sounds like (and what it sounds/behaves like when one wire is under less or more tension, because let's face it, that IS going to happen in the field eventually).
In the interest of simplicity as well as damage tolerance, have you considered attaching the guard to the trunnion by way of a heavy force fit? Once in place they can be pinned or screwed to the trunnion to ensure it does not back out due to vibration from firing.
thankyou
The closest to "machinist" I've ever been was my buddy with a 3d printer. This is fascinating as all hell!
BFHG is cool, got a nice ring to it.
Hey mark is there an engineering reason you went with aluminum extrusion instead of traditional CNC milling ?
Once established, extrusion is usually more cost effective at higher production volumes than machining from each one from billet. Not an engineering reason, but yeah....
I doubt it's so much an engineering reason as it is a speed and price reason. Still shouldn't be any less capable of handling the stresses though. Edit: 7:00 LOL as soon as I finished typing this he says exactly that. Go figure.

@@ChucksSEADnDEAD indeed. Not to mention it all wants to move and distort when removing so much.

How much less will this cost you per rifle with the hand guard being closer to near net? Just getting mlok will rile up all the nerds. Thanks
