Your barrel length comparison is a visual representation of why I stopped playing around with my barrel lengths and went back to 16
I’m swapping my 12.5 to a 16” sionics chrome lined. Stupid pistol laws and I’m done with it
In suppressed it’s the same length, Rock on.
Bro, you stated the purpose was for CQB. Velocity doesn't really matter inside of 50 yards for CQB because the projectile will still be above its velocity threshold in a 10.5”-11.5”. Suppressed weapons are extremely beneficial around mates, inside of structures, and within close confines, like a vehicle; it also allows for better situational awareness with the reduced blast. The added maneuverability is a bonus. As you said, guys with 16” barrels go unsuppressed because of how long the rifle becomes with an added suppressor. A blast from a 16” barrel in close proximity to a mate doesn't feel much different than an unsuppressed blast from an 11.5” barrel; on paper, yes there is a difference, but they are both loud and unpleasant in real use.
In CQB, the downside of short carbines is rail space for aiming and illumination devices; as you said, it compresses you.
If your purpose is for a general-purpose rifle that does pretty well all around but is better at midrange to extended distances, then a 16”+ rifle is preferred. The ballistics and terminal performance really start to separate itself from the short barrel-length rifles.
Velocity always matters.
@@frankopanklaric If the rifle projectile is within its performance threshold, it’s going to perform. If the chosen projectile is outside of its performance parameters within CQB distance, then different ammunition or longer barrel length should be considered.
He just want more space to do CQB lol he clearly doesn't care to think that smaller spaces exist and 16" barrels are just not ideal for them. He'd clearly like to operate only in more open areas where the ballistics are still a barely noticeable difference 😂
@@frankopanklaricJust get a Krink or an AK102
The 5.56 was not designed for CQB weapons and it’s ideal length is 20”. Arguing about 16 vs 11.5 is stupid because none are ideal bare minimum for that bullet is 18
The 7.62x39 and 5.45x39 don’t suffer from the same loss of velocity from shorter barrels and 14” are considered the sweet spot
@@frankopanklaricnah, even the mk18 with m855 will achieve hydrostatic effects out to something like 55m.
Punisher skull guy said it correctly. A 16” unsurpressed is fine for home defense which is thankfully a rare event. But people who fight in structures professionally are going to be running suppressed 10.3” or 11.5” because with the can, it’s about 16” give it take.

And sigmas pull out their sidearm and knife.
As someone who may or may not have put down 50-70k rounds in shoot houses over the years I can may be qualified to chime in on this subject.
Barrel length doesn't matter near as much as training and being confident that the people you are clearing a structure with are competent.
My first few years doing "practicing" cqb I used a 20" m16 A4 and it was a massive hindrance. Since then I have primarily used a 10.5 or a 13.7 and they are superior for being able to maneuver inside a building.
WE MAY OR MAY NOT HAVE ASKED
@@cardboard_shaftEat my shaft - he’s right
A con with shorter barreled ARs is that wear and tear is accelerated, the impingement is more violent than with a mid-length gas system.
You could always just do like a 12.5 midlength, wild idea I know but they exist and SIONICS has proven they work well.
@@TheHashtagSquad2K15 This is the route I'm taking. Every little bit counts in both directions.
@@TheHashtagSquad2K15be careful with the dwell time, not a big deal but lightly charged 223 loads might not be totally reliable once it’s dirty. If your running a suppressor a midlength is much better.
Only is gassed unproperly. Well gassed short guns have little downside as far as wear and tear is concerned. That is much easier to do with a 11.3-12.5. Yes most short guns are way overgassed but they don't have to be.
@@CheeseBurgerXJ haven’t cleaned it yet, mostly running 55gr unless I’m shooting for accuracy and then it’s 77gr. No problems with cycling. Yes I’m running a can but it’s a Flow 556k so it’s not exactly increasing back pressure
I’m glad you went into depth about concussion. That is the most important thing you need to talk about.
I only own/run 16 inch ARs as a cop in California. I don't run suppressed, so my length is maneuverable in CQB while still providing great ballistics at range. Sure, the shorter barrels are handier for CQB, but I'm not counting on exclusively fighting indoors.
You act like everyone owns ar’s “assault weapons” in your dis armed communist state.
thanks for being a cop in LA....definitely a scary world over their these days to be a cop
the cheapest 55gr is extremely lethal at 300m out of a 10” gun. don’t kid yourself
@@cardboard_shaft look up wounding ballistics of 55gr fmj. It has to have a lot of speed to fragment and blow up in the target. If it isn't going fast enough then it will ice pick and go straight through just like any other small 22 cal. 300 yards is out of fragmentation range with 10.5 barrels
@@keithcrandall1369 Correct. That said, 300 is out of proper frag range for (non-specialty) 5.56 anyway. The threshold is approx. 2500 fps (give or take for bullet design), and below that critical point the frag/tumble behavior drops pretty abruptly. Even a max-burn 24" bbl will keep most rds there only a little past 200.
In my limited experience, running a supressor is a must if you're running 556 or 223 in doors. One thing allt of guys dont talk about is your body size. Im 5'7". Im in decent shape but its still more diffkcult for me to run a 16-18" with supressor vs a 11.5 with a k can.
I don’t have orangutan arms. What is ergonomic for some is not ergonomic for others. I like a stock 2 notches back (or first notch on a 4-pos tube), and never use longer than a 13” handguard. A 10.5” handguard brings me in a little, but it’s actually easier to point the shorter barrel with the center of mass closer to my body. SBRs are more ergonomic for me.
I never left the 16 & 20 guns. I never had any interest in anything shorter. I did get a IWI Tavor for something more compact. For anyone who wants to do CQB, you'll just end up dead. Its like getting involved in knife fights.
guess i’ll just never go inside of a building ever again!
@@cardboard_shaftdumb response
@@traceyevans2757 dumb comment 🥱
Interesting discussion. However out of all the comments here I only saw one talking about how easy it is to get done room clearing, even by someone who has had minimal training. A friend of mine got wet when the man next to him (his long time friend) took one to the head. He got wet again when he took the short range shot into the shooter. I thank God I’ve never had to share in that experience.
Seriously, what do people actually expect to be doing.
I honestly this this discussion is really only relevant to people have have trained with military or law enforcement… because I’d you don’t know what you are doing, you are just going to get yourself killed or someone else killed.
Yeah you are the 2nd comment that has brought this up..
I believe in the 20” gun with every fiber of my being. Mainly because it turns training ammo into duty ammo and is really easy to shoot and easy on components. I take the AR as Gene Stoner envisioned it, because he knew exactly what he was doing.
Why is there such an overemphasis on CQB? Also, why are suppressors presented as the only solution to potential hearing damage? How difficult is it to keep some earpro next to the rifle if you need to use it?
Marines did it with 20", im sure ill be fine with my 16"
We also used to fight with swords and spears, then later stood toe to toe and shot each other with flintlocks. Just because someone did it before doesn't mean we have to handicap ourselves.
So what say you?
@@Unholy07 3.5 to 4.5 inches is definitely NOT a handicap.
And WWII soldiers cleared buildings with M1 Garands. Doesn’t make it a good idea with current advances.
@pb7087 not every fight is cqb. 14.5 to 16in is optional for what ever Suze you want while not degrading 5.56 performance, though 16in is the most optimal. And for longer engagements, that extra 1.5in is gonna do wonders for troops. If you really want it smaller, calapse the stock if your raiding a building.
In my unit, we went to a pistol light works well. Did a few modifications. Did you know Ashley made a new light that is about 4 mm thick and flat has a 2000 luminescence and will be hitting the market in 2026
If I was ever unfortunate enough to have to do any type of CQB, I’m definitely going with the 7.5” 300 subs, and can easily go to 200 meters with a mag swap to 110 grain supers.
If I could only pick one rifle for some reason, I’m going 16” and bayonet 😆
I run 16” because of less legal hassle, you get use to maneuvering, doesn’t get hot quickly, being issued both the M16a4 & M4 in the Marines the 16” barrels feels like an M4. You eventually learn to deal with a longer barrel whereas the shorties you tend to cheat a little.
Another thing people don’t often talk about is that SBRs get hot very quickly after one magazine. And I mean very hot. What’s ironic, people don’t want to hold a long barrel rifle for a long time because it’s front heavy. People also don’t want to hold an SBR for a long time because of how hot it get.
I run a pinned 15.9
I've ran a 16" for so long now that going with anything shorter just feels odd. I've definitely trained with way shorter and taken indoor and low light classes with shorter but now practically all training is done with a 16".
BUT.... When running suppressed I've been sticking with a 12.5" with a surefire can that turns the barrel into a 16.5". I tried running a low light course with my LWRC 16" with suppressor and it was definitely too much.... Kept getting stuck in corners and bumping my rifle off of walls. Switched back to my BCM 12.5" suppressed.
To me this is where Bull Pups shine. It is the sole reason I got my X95. I can run a 16" barrel with Suppressor, for the same length as an 16" AR. The weight towards the rear makes holding it much easier and can be one handed mush easier.
Shortie 300blk is the answer
All day long!!!
Then if you need to fight outside the house then your handicapped
Aren’t cons 1 and 2 for the 16” the same thing? #1 is length, and #2 is maneuverability. The length is what causes the maneuverability problem.
16 inchers are very dextrous, it just depends on arm length and handguards. the downside of length is that it doesnt fit well in small spaces which applies to everyone, the downside of 16in maneuverability is target transition and acquisition, which can also be caused by weight (like those 12 pound 10.5s). with a suppressor on the 10.5 the 16 is more manuverable because you (should) have more rail space to grab further out, but without one the 10.5 has less weight overall so it manuevers better (assuming a standard of 1inch from handguard to barrel end for both guns).
Length isn’t just an issue for maneuverability. Ballistics and velocity are key factors also greatly affected by length. While that doesn’t translate to a CQB issue per say, it does translate to a big problem outside of the building settings trying to reach out to a rooftop or window 300 meters down the block at the guy trying to hip spray with an AK.
@@dreb222 yeah, he mentioned ballistics as a pro for the 16 and con for the shorter ones.
You guys over think things. Grunts clear rooms with 20” guns. Just train and do CQB…don’t over think it
@@Flashhideronlycqb is shit with 20” guns and they aren’t suppressed, a huge disadvantage on the modern battlefield
A 277 fury from Sigg sure fix that problem, I do see what you’re talking about. You know better as I weapon is a tool. You got to bring the tool to the job long as you know what you are dealing with
For me, 14.5" or bullpups for cqb. Everything is dependent on training.
Seems training and equipment talks only apply to ARs. This is where the bullpup shines. Triggers are improving as of late, and they are heavier, but my 20” barrel is still shorter than a 16”. There’s still improvement to be made, but really, I’m tired of feeling like the one and only option is an AR
13.7 it is, 300 BLK Out!
300 Blackout is every bit as capable as 5.56 in an anti-personnel role such as law enforcement or home defense, but it is capable in some other ways that 5.56 is not. The heavier, larger projectiles give the 300 Blackout good kinetic energy and make it a better choice for use on medium-sized game.
Tavor is 16 inch BARREL and is 26 inch overall just like a -10.3 ar15
Yah but bullpups suck. They don't have rail space. Mounying optics sucks. The ergos and manual of arms suck. Parts availability good luck. The triggers suck. And they just aren't as reliable because there is less testing on them.
X95 with a super sabra and upgrades is fantastic. Plenty of rail space and short. The 18.6 is a happy sweet spot.
@@John_439 Just saying it's and option
I totally agree with you. I can run my suppressor with my 16" barrel for the same length ARs run just a 16". There is a reason Israel uses them. They fight CQB probably more than any other country.
@@John_439 It seems you never used one. Trigger on mine is a 3lb same feel as with my Geissele on my DD 16" AR. I have plenty of rail space (you can only mount so many things before they get in other accessories way), plus built in BiPod (BLK LBL). The only drawback is it is about 1.5moa worse than my DD, and relearning the mag change, the safety, mag release are the same as an AR. I like the side charging better than the rear charging on an AR. But like you said do you need that accuracy at 15yds. The X95 is my go to rifle. Try to one hand a AR, the Tavor is pretty easy.
Love the 16”! 😃
Best settlement for this overall is… what do the people that do it for a living, and have the choice of equipment, what do they use
Can you do “CQB” with a rifle the length of an English claymore? Yes. Is there better sizes out there? Yes. But the real question is what are you considering CQB and what is the likelihood of you going from areas with distance to up close 7 and in. That should be the real decision point.
This exactly…
Even if end of world scenarios is on… I’m probably not clearing bourses often..
Like many have said..
It’s not a movie or a video game..
My ar is 16..but still loving the sogneattler in 300 BO. 16 is doabke and of course better at range; but i wouldnt feel underpowered close up worh the rattler
Great information 😊
Lasers that’s a good one. We are actually moving away from lasers now because the enemy has make vision and and thermals now they can see lasers now we’ve been moving away from them back in 2019
It is so easy to get a can these days friends should not let friends shoot unsuppressed
And I hear you on the extra rail space. Buy my guess is you are tall as shit when most guys are not
Yes he is a tall human as you can see his waist is at least a couple of inches above the table and most tables are 3 feet tall.
Honestly a 11 inch rail is fine for most people. I'm just under 6 foot with long arms and it isn't a problem. Now, I can't run a bipod but that isn't really a concern on a cqb gun but everything else can mount up just fine including a lpvo if that is what you want.
The 11” hand guard is perfect for me, unless I have a laser on top that forces me to only use 7” of it. That’s when ergonomics really become an issue.
Funny that was same thing I used to measure.. he’s 6-3-65
I prefer 30” barrels and a 10” can for cqb. More velocity.
300blk 8.5 inch with a can… way too smooth 🔥🤷🏻♂️
This. 8.5" 300 BLK running 110g supers is ballistically equivalent to a 14.5"-16" running 55g. He should not have discounted the "tiny PDW's" when it gives the best of both worlds.
Ran 13.7 10.5 14.5 12.5 and 16 settled on 12.5 I feel like I here everything from it I need and still maneuverable and it doesn’t have as much concussion or flash with my nox
Awesome review
Both my RUGER PC chassis carbine and Steyr AUG have 16" barrels. Both have "optimal velocity" from those barrels.
But my AUG is a bullpup so has a shorter overall length than even the short barreled M4. But GREATER velocity.
A 20 inch ar with a fixed stock is shorter than a mossberg 590 with an 18 inch barrel.
I'm not saying it's bad to talk CQB. We should. I'm just pointing out that while it's sexy, it isn't ideal. I forget where I heard the stats, but lead man has a very good chance of catching a round at some point during CQB work. If you do it long enough, someone will eventually get shot, doesn't matter how good you are. What real life situation would you be doing CQB? If you do, you better have a whole team of goons backing you up and top tier trauma care available... Are you going to have that when YOU do CQB for real??? Probably not. Look at what the Taliban did in Afghanistan. They were lobbing PKM fire from outside of M4 range. Naturally, the most survivable form of combat is the long range stuff... Obviously there are exceptions, if you get your door kicked in at 3:00 AM, then you're going to do CQB... But that's an unfortunate example of the battle choosing you instead of you choosing the battle. Choose the battles you can survive. Choose the 16 inch.
For CQB better use 16" barrel with a bufferless and collapsable stock, like a Sig MCX Rattler, CMMG Diseent, SCAR, CZ Bren, Fox Mike etc.
Why have a 16 inch barrel with a 3+ inch muzzle device, would it be better to use a 20 inch barrel with just a thread protector?
2:33 by hearing safe do you mean it’s not even hearing safe with hearing protection on?
Would a 16” 5.56 with a supresor be hearing safe?
My 14.5 P&W should be done by the class. Is running that unsuppressed acceptable, or should I run it suppressed? I ask as I'm wondering if the simunitions will gunk up the suppressor. It's a HUXWRX and I don't have a training can for it.
I have always wanted a 14.5 inch barrel and an 18.
Good video.
I personally think this why you should own a 16” and a 300 blk. The only advantage a shortie 556 on the 300 is range… which defeats the reason behind the shorty 556. Unless you live in a giant metro city you’ll likely never have a reason for a cqb weapon meant for kicking doors. Get a 300 and call it a day
If 13.9 was an option from the company I bought my upper from I would have done that, but the 14.5 I did get is not bad.
Speaking only for myself:
I have zero desire to fire anything but sub-sonic rounds within ANY kind of confined space 😫
So, for me, anything shorter than a 13.7~14.5" bbl doesn't make any sense.
A suppressed 14.5" makes for a nice 100m carbine.
Couple a 13.7~14.5 with a 18~20", and I'm solid 😎👍
Shooting a super sonic round in a house sucks ass . But generally the louder the pop the faster they flop
If flagging your partner is a worry you should train more that is a skill issue. Basically every point boils down to a skill issue. And concussion is mute just run a 11.3 with k style suppressor it is better in every way than a 16 in cqb. Barrel length does not matter at cqb distances. And I am 5'11 and have long arms and a 11.5 with a 10.5 rail is plenty of rail space for everything I need to mount on it.
Trigger finger is also a skill and discipline issue. But why we must have the safety on and finger off the trigger all the time. Because your nervous system will force you make mistakes under pressure. We are human, so if there is a procedure or gear setup can prevent this incident caused by human instinct, why not use it?
@@eenzyme898 because that gear is objectively worse for the job. If you are worried about that you shouldn't be clearing rooms. And I definitely wouldn't clear rooms with you if you are worried about that.
@@John_439 I bet you don't know the three physiological reactions that cause people to squeeze the trigger involuntarily. Your arrogance and ignorance of science will cause your partner to get hurt. So yea, I’ll never team with you either.
@@eenzyme898 lol you have no training. You are obviously a boomer. Catch up with this centuries technology and then @ me
I mean. 12.5 performs almost exactly like 14.5. In velocity testing 12.5 is a sweet spot imo. With a 5" suppressor, just feels perfect
It’s more comparable to a 14.5 Velocity but still not that close. Especially past 200-300
"almost exactly..."
That is cope.
Sick cope. 12.5 guys say they get 14.5 velocity. 14.5 guys say they get 16” velocity. So internet tells me 12.5=16” velocity….. nice
12.5 is basically a 20” gun according to the internet
@@cardboard_shaft so is your mom. Get a chronograph and test for yourself. They are cheap now
it's not the size of the barrel, but how much you train with with
Training wont overcome ballistics
@@korcommander ballistics don't mean squat if you can't hit the target.
@@crackbot And its harder to hit a target using an intermediate cartridge when its more affected by wind and drop, and the shooter by concussion and potentially shorter sight radius.
Is the first gun 10.5 or 11.5 because I think u kept saying it was 11.5
Yeah 11.5, 10.5-12.5 category
If the odds favor you NEVER having to "operate" in a CQB environment, then a 16" barrel is great for whatever you're doing-- including that .001% off-chance of you HAVING to do CQB
Can I get an ID on the handguards used ?
I'm just gonna continue to train with my M16A4.
If you run short 5.56 youre decades behind. The 77gr you need to even be competitive is the same price as .300blk and you still need a longer barrel. Trying to make the wrong tool fit the job is the governments favorite passtime, but chances are you wont actually do any cqb ever and shouldnt look to because its a good way to end up dead
If you enjoy shooting off a bench or prone at the range....100% get an 18" barrel, bc the rifle length gas system will make it a JOY to shoot.
And if u pair that with a JPSC, Low Mass BCG and a decent compensator it will be softest rifle you ever shoot.
However, if you ACTUALLY believe that you will be clearing houses doing CQB someday (bc Call of Duty looks cool and retired SEALs now teach classes on CQB) OK then get a 10-13"
It honestly depends on suppressed or non.
16 YES.... put stock at shortest position and the 16 becomes a short weapon. In CQB your not going to have forward arm fully extended anyway ask the guys using a 10" barrel guy. A 16" w stock in short you get all the benefits of a full size weapon in CQB. Just set your dot at front of receiver. Ask any grunt who worked in the real and ask them if ALL fighting is in the living room of a house or if there is some street fighting or out in open areas. So having a do all is better than a special purpose rifle built for just a living room.
10" or 16" even the most advanced militaries in the world get F'd up in CQB situations

The average American who owns one AR, and wants it set up “nice” would be best benefited with a short gun with a can. 10.3 loses a lot of lethality after 50 yards, however still capable out to 300. Especially with proper ammo choice (69-77 grain projectiles) Short of the world war 3 in the US. A short gun is all you need.
If setting up a short gun is too much to think about just get a 16” gun. If you want full ballistic potential get a 20” gun.
Pros and cons to them all but figure out what realistically benefits you the most.
Overall, your video is good. There’s some things I have discrepancy about but the biggest discrepancy I’m gonna put are you talking about in general or are you talking about law enforcement or military? Those are two different animals in general you know that means but I want to say what mean by that is civilian like civil unrest. Did you see the movie Civil War? That was some horrible fighting with a Boogaloo boys
Sbr is best for qcb
I have NEVER had an issue clearing w/ a 16 inch barrel in CQB/CQC. Although I have used shorter barrels the 16 has always been my steak and potatoes 🤜🏾💥🤛🏾, stay safe shooters✌️
I’ve always been curious and wanted too know,if you’re using a 7.5 223/556 AR is what you gain in movement is lost in efficiency of the round? At that point should you just use a 9mm AR/PCC?
At 7.5" the 5.56 is still far more lethal than a 9mm. You're talking 1000fps difference, basically double the kinetic energy
@@TurboManTomwhich doesn’t matter when it’s a tiny bullet ice picking because it didn’t frag
5.56 is not a good round in a short it wasn’t designed for it and people who argue otherwise are coping
The wound channel from 9mm hydros is going to be far greater we have ballistic gel tests showing this
Hell even .22mag seems to perform better than 5.56 on soft tissue
@off6848 it very much does matter. The trauma cause by an object moving an extra 1000 fps through the human body. There's no "coping" lol goofy language.
You're not considering potential for targets wearing body armor, which is very normal in the arena that you would be clearing a house and shooting close range. 9mm fails when you need a round to succeed if your running into that. It's pretty clear when operators have pretty much all gone to SBR 5.56 instead of picking up an MP5
@@TurboManTom the energy on target of a 55 grain bullet out of 7.5 is 488 foot pounds at like 2,000FPS…a 115 grain 9mm at 1,300 fps is 431 foot pounds,on the target.its not a huge difference. I was more wondering if your going to get good bullet performance out of the .223/556 on the edge of the FPS it requires to do what it’s supposed to,versus a a decent 9mm. I’d just like to see the comparison in gell.with some different bullets of each caliber.
@adamadams6740 I'm not sure where you're getting those numbers from. Muzzle velocity from a 62g 5.56 out of a 7.5" is about 2200 fps which is 904 joules of energy or 666 ft lbs. The 9mm 115g at 1300 fps is 585 joules or 432 ft lbs. I'd say 230 ft lbs is significant.....however, 9mm is less capable everywhere else as well. And the lethality in a human isn't only measured by the permanent wound cavity the temporary wound cavityis also a huge problem for living creatures. If you take a 5.56 near your liver or lungs you have a large chance of lethally damaging that organ. That's less of a risk with 9mm. 9mm works for sure, but the loss in efficiency in a 5.56 is not enough to throw away the advantage it still has.
I'm 5'2", that should tell you everything. However, I do run any size.

I use a cz scorpion with a full Wolfman suppressor. It's essentially a rifle with that full surpressor on it.
But running it with 147 self defense ammo I don't need that 16 inch rifle barrel for a cqb. It's basically a better pistol. Dudes aren't breaking in with rifles
Have we just forgotten about 300blk?
,300blk isfor a very niche purpose only. Yes it's great on shorter rifles and such here and there but not everybody has a .300blk and the ammunition is expensive compared to 556. Also .300blk sits in the PDW catagory
@@Chris09978 cqb is a niche category. And why would it fit in pdw a 7.5 inch-10.5 inch 300blk is definitely not pdw size. Even a 5.5 is really to big to be a pdw. For pdw think machine pistol or mp7 or maybe mp5k. And cqb is the most dangerous firearms thing you can do i think the cost of a 300 blackout upper is justified.
@@John_439 I'm talking about teh caliber nit more so the length of the rifles, and ,300blk is technically a pdw because it is a necked cartridge not a rifle round
@@Chris09978 what, no it is most definitely a rifle round. It has the same effective balistics as 762x39 with supers. It was designed as a rifle round
@@John_439 ballistics and velocity aren't the same necessarily. The ,300blk is meant to be shot out of those those shorter barrels that's why a lot of .300blk are in those shorter barrels like 5in or upto 7-8in barrel lengths 5 in is the sweet spot for .300blk. It's true that ballistics are the same but it needs a shorter barrel to be more effective not longer barrels. That's why he didn't mention .300blk because most agencies and Military are using them as PDWs. A another reason why .300blk is considered a necked cartridge is because it because it does very very well at subsonic and doesn't break the sound barrier. I doesnt have the same velocity or FPS to be as close as a 7.62x39 or 556.
7.62x39 is about 2300 fps
556 is 2500-2800
556 needs at least a 16-20" barrel to actually be considered effective
7.62x39 not so hot with those long barrels but it's really good at those shorter barrels.
So yeah .300blk is not a rifle round
5 extra inches of barrel, is a bit of a suppressor
Roscoe 13.7 is true kvlt
Just get one of every length
Barrel length, the only time men are happy being shorter than the other guy.
13.9” .308” has entered the stack
Just get a Krink or an AK102
The 5.56 was not designed for CQB weapons and it’s ideal length is 20”. Arguing about 16 vs 11.5 is stupid because none are ideal bare minimum for that bullet is 18
The 7.62x39 and 5.45x39 don’t suffer from the same loss of velocity from shorter barrels and 14” are considered the sweet spot
AR you platform is designed to be a medium range rifle 200-600 yards effective
The AK was designed to be a submachine gun 0-200 yards effective
I don't like the idea of "nerfing" a bullet for the sake of "operating". High speed low drag sounds ironic when shorter guns literally shoot that bullet SLOWER than a full sized barrel. Teammates, hearing, convenience in general should all take a backseat to effect on target. I would want my bullet to go as fast as possible and do as much damage as possible.
Optics, lights, grips, lasers all add drag imo
A clean AK102 is the way
16” is the way. No Gov’ment involved.
👍
I live in NY... not much of a choice 😂
If you need a longer barrel to NOT SHOOT your partners.....it's an operator issue and not a barrel issue
There’s a thing called hand grenades & laser guided JDAMs for a reason 😂
magnificent paintjobs on your rifles
I got a video on that too😉
Alright armchair generals. Relax. Let the man cook
Meh, prefer 10.3-11.5 with a K can but you do you. I'm sure SOCOM agrees.
If you are muzzling your buddy, you have zero situational awareness and probably shouldn't be clearing rooms. 4:46 just saying
14.5. Problem solved.
Because everyone here is having to clear rooms all the time…. Lmao
Now we go into partner you say you’re in a team right a team right are you talking about a partner that you never worked with? That’s also in a different team right then you should know better. Same training communication even this is military law-enforcement you always do runs right so in that aspect, there should be nothing said about it now if it’s a random dude like Ukraine, for example or different country or 2020 BLM riot. Different person no training then that’s a different story.
Dude. You already said that. We get it!! Worst comparison ever. I'm salty I even gave you a view.... 🤡
The way I look at it, 16-10.5, 7.5 is the shortest I'd say is ok
Reduced lethality with the shorter barrel lengths and reduced adaptive capability
🙄
Umm I'm willing to bet if someone takes a 77gr otm from a 10.5 to the snot locker they're going to be equally as dead had that projectile come from a longer barrel shot placement wins
At 25yds and in (cqb ranges) barrel length does not matter. 77gr otm will smoke you no matter what. Sure out past 500yds my 18 inch does better than my 11.3 but inside a building it does not matter. All modern ammo will frag from an 11.3 barrel or greater within cqb distances.
@@John_439 and there’s the problem. The M18 was designed for CQB, now take that outside to carbine ranges and it’s crap. It’s too mission specific. “All modern ammo will frag”……. That’s BS. M193, M855, M855A1 will not “frag”…. You’re showing your ignorance sparky.
@@HDBujutsu1775 a 11.5 barrel gets 100-150fps gain over 10.3 mk18. And yes modern ammo will frag. M193 and m855 is not modern ammo. Even then from the speed of a 11.5 barrel (the new standardfor army and fbi) m193 is over its minimum frag velocity at any distance you will see in cqb. We are not civilians tied to the laws of war. We get to run the cool stuff and since cqb is the most dangerous part of gun fighting there is you want every advantage possible. With my 55gr BTJHP hornady hand loads 9ut of my 11.3 barrel they are stated from hornady to frag out to well past 300yds.
Use any lenth you want who cares what anyone else thinks
Barrel length 5 inch under 50 yards .
10 inch under 150yards
16 inch over 300 yards
Trades off per inch in QCB
