20" barrel a meme?

Is a 20" barrel on an ar15 really magic or are the 14.5" bros right about it being a meme?

      Even with 20" barrels an ar15 isn't ideal past 300 yards. Honestly who gives a shit what barrel length you have. I shoot a 20" because the recoil feels like a nice loving little nudge on my shoulder.

    depends what you're trying to do, but 20in isn't magic or some shit
    barrel lengths are tailored to a goal or job
    all my most used guns are like 10-16in, the 20 is just a range toy
    people with 20s will try and say anything else is wrong which is just moronic, that's what someone with only one gun would say

        This dude said literally the exact same thing as me, and it wasn't saying nothing, it was speaking the truth

        Of the ten ARs I have six are 20” guns (A1 kit build, A2 spare parts build, Colt SP1, two Colt A2 Sporter II Govt models, FN A4 covered in KAC) and although I love 20” guns and they’re by far my favorite ARs to shoot they’re still just range toys. I would never choose one of them over one of my 11.5s or 14.5s in a real life situation. If I’m picking a gun for the pure pleasure of shooting it it’s really hard to beat an A2 from the bench using irons at distance.

    It's a meme outside of niche uses. If you want to stretch 5.56 out a bit then you're better off chasing better bullets than barrel lengths past 16". If you're some sort of moron who's both obsessed with minor ballistic performance increases and insists on using 55gr FMJ then it sort of makes sense.
    >But why not use a 20" barrel AND better bullets
    Because nobody cares about your copemusket and the vast majority of loads are designed around SBR barrel length performance or carbine length. Stick them in a 20" and they can under penetrate or just behave erratically at close distances.

        I’m not a “carbine guy.” I have 20” 7.76 NATO rifles. They’re great. I’m also tall. It’s simple math, 5.56 doesn’t really have the powder to benefit from 20” barrels excepting in instances where you’re doing shit 5.56 ain’t really designed for and thus you’re hindered by the cartridge itself and not the barrel.

          As far as I'm aware barrel length should not effect stability to a large degree as long as you're using an adequate twist rate.

          • 1 year ago
            Anonymous

            Velocity does affect stability to a decent degree. The faster the bullet moves, the faster it's spinning (assuming the same twist rate). A 7% increase in velocity translates to 7% faster rotation. You can stabilize a round with a 1:10 at 3300 FPS when you need a 1:7 at 2200 FPS.

            I remember the .224 Valkyrie having trouble stabilizing in 1:7 barrels when it first came out. People were saying Federal fricked up the recommended twist and it needed a 1:6.5. It was later found that this was due to morons using their "suuuper long 18in barrel" when the cartridge was built around a 24".

            Barrel length is a massively overlooked criteria for stabilization when dealing with higher weight projectiles. I recommend a 1:7 for anybody that wants a 10ish" barrel even when the meme charts say higher will be fine for this reason.

                Math doesn't add up unless there's some weird coefficient that only shows in massive gaps in velocity. The 1:8 would only be doing 180k RPM while the 1:10 would be spinning at 554k RPM. The 1:10 would only need 2500fps to spin the same speed as the 1:8 at 2000fps.

                I think the calculator assumes that a higher velocity requires more spin to remain stable, which is probably true in general. But hypersonic is well beyond the meaningful ability of the calculator to know what's going on so it's just giving bullshit values at that point.

                Its literally just using the Miller twist rate formula and plugging the values in. Any velocity above 2800 is very quickly getting into diminishing returns in regards to its effect on stability. For example if you shot the bullet at 5600 FPS, its only going to be 26% more stable than one launched at 2800 FPS

                Anon this formula was derived from empirical data and the dimensionless values were just selected to make the formula fit the data. If you could review Miller's data, you would find that little or none of it was for small-bore bullets fired at above ~3000 fps.

      For those extra 4" of barrel you move the target ~50 yards closer in terms of effects on the target, seems pretty based to me.

          snug against the FSP; that has 2" of bbl still exposed I think. Gordy can is like this, but there is full 14.5 underneath (pic is 12.5 which works for AEM5 to be flush). 14.5 carbine FSB is same as 20 rifle FSB so it should work

    Paul Harrell has made a couple of videos on this. IIRC the difference between 20 and 16" is small but measurable, and the difference between 10.5" is significant.

    Also I think some ammo doesn't "tumble" the right way out of shorter barrels. Like 223 is supposed to tumble through a target and create a large wound but apparently some ammo doesn't do it right out of a short barrel.
    But it probably doesn't matter in most cases

      It really doesn't, especially if you actually select the proper loadings for your barrel length. Sure 55gr is phenomenal out of a 20" barrel, nobody is forcing you to use it in your SBRs. We have plenty of heavy, fast burning rounds for them these days.

    Of the ten ARs I have six are 20” guns (A1 kit build, A2 spare parts build, Colt SP1, two Colt A2 Sporter II Govt models, FN A4 covered in KAC) and although I love 20” guns and they’re by far my favorite ARs to shoot they’re still just range toys. I would never choose one of them over one of my 11.5s or 14.5s in a real life situation. If I’m picking a gun for the pure pleasure of shooting it it’s really hard to beat an A2 from the bench using irons at distance.

          I just don't understand why you would ever get an 18 in. Either get a full length 20 in. rifle or get a 16 in. legal minimum length. It's only 2 inches shorter so you might as well get the most out of having a long barrel. To be honest, whenever I see an 18 in. barrel I just assume the owner wants to feel 'special'. Unless you're specifically trying to clone something like a Mk. 12 SPR there is no point to having an 18 in. barrel, in my opinion.

              Um, yeah... that's literally the point... there's no reason to get an 18 in. when you can get a 16 in. for cheaper, it's far more common and has far more variation in barrel types and profiles.

                Not really. You can get an 18" barrel in pretty much any profile you can get a 16" one in. LW, medium, heavy, government, fluted, weird proprietary ones like faxon's gunner profile. It also costs pretty much the same. Commonality isn't a real benefit either. One other big benefit of the 18" is that you can use rifle length gas without reliability issues.

                I still think 20" barrels are superior for line infantry/patrol cops. Dynamic entry is only necessary if you're in a situation where there are possibly civilians present. In a military context, where I need to seize a building I'm using frags. Worried about civilians? Toss in some CS first to get them to scatter (this is permissible under the Chemical Weapons Convention).

                CQB isn't the only application for a shorter barrel though. Getting in and out of vehicles was the primary reason rifles rapidly got shorter with the implementation of things like HMMWV's. Plus a short barrel chops a lot of weight off. But I agree, a lot of them are just too short now. In my opinion 14.5 is the perfect balance between velocity and maneuverability in a 5.56.

    20in barrels are great. If you get one though, get one with a thinner profile barrel. They tend to get heavy. Especially if you tactitard out the rifle. I wouldn't run a rifle out in the field past 20 inches. Now for a bench gun? 20 inches is the bare minimum for rifle cases. You should be bumping that up to 24" for the bench.

    First of all, everything below 20 inch is gay and for weak little zoom-zoom larper homosexuals. Second of all, i think alot of people underestimate the real advantage of 20 inches: The best gas system. A Rifle length gas system is objectively the most reliable, long living gas syste mthere is. It gives you superior lifetime, reliability and recoil. Read the "100 000 Rounds AR15 Test" from Battlefield Vegas, at some point in the discussion they bring up rifle length AR15s. He says that to this day they have never broken one. That has reasons

    There are many factors that influence barrel selection, including length, twist, profile, and gas configuration.

    Will the rifle have a suppressor

    55gr M193 out of a 20" barrel *will* punch holes in dudes wearing level III steel plates, while also having gentler recoil than 14.5". Even with a A2 stock, the 20" barrel has a shorter OAL than a Mossberg 590A1 with the 18" barrel, so it CAN do home defense.

    That being said, they do suck in confined spaces when you're trying to do high speed violence of action type shit, but honestly unless you have to hit buildings as part of your job, I think it's an acceptable trade-off.

    Garand thumb talks about how a 20" barrel turns 55 grain training ammo into defense and fighting loads. Something thats been known for a long time but its nice to see it be acknowledged current day by a high volume experienced shooter.

    I really like twenty inch barrels
    I think they’re far more practical indoors than many imply, especially those with cans on a 14.5

      unless you're playing CMP High Power, bull barrels on AR-15s make no sense at all.

          you can't quick change the barrel on an AR. This is pure LARP, but indulging you for a second, you'd want a HBAR AUG at that point, because you *can* quick change barrels on an AUG

            Did you read the part where I'm west of the 100th parallel in open country? What is larp about patrolling a 2 mile section with a 20" bull barrel and a binary? If some kind of bundy shit went down i could lay down extended fire without issue.

                no you won't. If you had any sort of training you'd know that this is a fool's errant.

                Larping is war gaming out possible scenarios that could happen. If you don't war game then you are surely going to stove up when shit goes down for real.

      People overlook location way too often when discussing this. Western Nebraska is open as frick and a longer barrel is better. Spend $500 (or more) and get a 10.5” to keep inside the house

    The biggest thing that matters between barrel length is barrel harmonics.

    Too long of a barrel with bad harmonics will induce inaccuracy while a shorter barrel has less chance to frick up the shot.

      fixed stock? standard rifle buffer
      adjustable, H2 buffer UNLESS you're running an A5 or UBR stock. In that case you want the A5 buffer with rifle spring. This is what I use, and it works reliably.

    Make it a 20”. I mean really. You are choosing to use a bullet that is VELOCITY dependent. No matter what kind of 5.56 or .223 it is, it is VELOCITY DEPENDENT. 55 gr, 62 gr, 77 gr, all of this depends on how fast the bullet is flying.
    So.... WHY CHOOSE to use a shorter barrel? Why willingly cuck yourself? If it's because you think the 20" is too big or heavy then... well... Maybe you should go to the gym, instead of the FFL. I mean really, the bullet was designed around a 20" barrel.
    And no, I really don't give a shit what SOCOM or other ZOG bots use. All of that war on terror is just myth and garbage. Imagine believing Osama is actually dead. Lol.
    Anyway, tangent over, the 20" barrel is the way to go. If you can't afford a long barrel, then save up. Don't be stupid.

      I assume your opinion is the same in regards to 7.62x39, right? After all, it was also designed for a 20" barrel and loses a similar amount of velocity when the barrel length is reduced.

      Out of all of those literally only 55gr needs to be going stupid fast to do what it's designed to. Your premise is literally wrong. Mk262 and 77gr OTMs are literally DESIGNED to be fired from short barrels.
