Are 16" actually the best all around?

Despite the fact that 16" is the shortest legal length without going through the ATF, are they unironically the best length? They are short enough to be light and handy but are long enough to retain accuracy and velocity.

I dont see much point in having a 5.56 gun shorter than 14.5" or longer than 18"

After 18" the velocity gains are not worth adding any more length, and shorter than 14.5" is reducing velocity too much for a round that is highly velocity dependent.

Am I right or am I just a cuck coping with the fact that I cant own a gun shorter than 16"

    No it's a good length. 95% of the velocity of a 20 inch barrel, but 80% as long.

    I would argue that 14.5 has 92% of the velocity and loses another 1.5 inches, but 1.5 inches is really not worth the $200 tax stamp. Anything shorter really starts to lose velocity fast, and Mk18s are going out of style rapidly as operators realized that 10.5 inch barrels really are too short for anything other than an entry weapon. 12.5 inches is currently en vogue, but I honestly think if you need a weapon that short in 5.56 you should just bite the bullet and go for a bullpup.

      Interesting and sensible take

      Would you say a 14.5 pin/weld is worth it over a 16?

        If you like the look, sure. Problem is that you now have a barrel that is as long as a 16 inch without the muzzle velocity or the ability to accept attachments like silencers (if you have one.) Honestly though, the difference between the two is basically splitting hairs. Go with whichever you like more.

              is attached to a barrel by means of welding or high temperature
              silver solder having a melting point of at least 1,100 degrees
              Fahrenheit, is considered to be part of the barrel for purposes of
              measurement. A seam weld extending at least one-half the
              circumference of the barrel or four equidistant tack welds around

                This is horrible advice. Pin and weld builds are a thing to get around SBR laws. If you grease someone with a P&W rifle, the cops are going to hand it over to the ATF, and when they get it in their hands and can visually see that the muzzle device is not pinned and welded, they're going to rape your ass for having an unregistered SBR.

                Never mind the fact that Loctite isn't good for installing suppressor mounts (even the high temp stuff). Use Rocksett.

                Years ago I did a 14.5 build. I agonized over the best way to do this without changing the heat treatment of the bbl. It was actually rather simple. I used silver solder as something of a lock washer ICW an actual lock washer. Then I danced a MAPP torch over the solder just enough to let the solder flash. I know that is not how you are supposed to apply silver solder. I also know there is no regulatory requirement for proper craftsmanship. I permanently attached it with 1100 degree silver solder per the law.

    16" is the "best" for anything you could think of, if you want to suppress your rifle it will make it the same length as a 20" or 22" barrel. 20" barrels are for milking as much practical fps out of most loads.

        13.9" is just the best length if you want to do a pin and weld build, so that it's legally a rifle and not an SBR.

        14.5" is still good if you don't want to use a muzzle device that acts as a suppressor mount. There are a lot of muzzle devices that are shorter and cheaper than the Surefire 3/4 prong, although I'd argue that even if you're not suppressing, they're still great muzzle devices. The Dead Air 3 prong is cheaper than the Surefires, so that one would probably be the best option if you know you won't be getting a suppressor for the gun.

        Otherwise, if you go shorter, you're either going to need to pay the tax man and register the gun with the ATF, or simply live dangerously, as any Free Man would.

        Wouldn't a bullup design with a 16" barrel defeat the SBR crap?

        They do, but bullpups are all kind of shitty, IMHO.

        Can someone explain what the issue is with lightweight barrels and suppressors? Thinking of mounting surefire mini on a 20" pencil profile. People are saying it's retarded but won't give an actual reason.

          I used to hate bullpups. I actually like them a lot now. Most of that comes from comparing them to an AR. Manual of arms is different, but doesnt seem to matter when talking about lever actions, bolt action or pump. You learn to use that particular weapon. The X95 has made it a lot more similar.

          People that complain about the triggers are either parroting info they heard or have target triggers on al their rifles. They are on par with a mil-spec AR trigger.

          Then again, I don't buy my guns expecting SHTF or an expectation I'm going to be operating. I like them for how they operate. They are nothing more than a range toy.

      Kinda, but a bullpup with a shorter barrel could be even smaller with a shorter barrel. Depends on how big the SBR is and what velocity/barrel you find acceptable.

    "Going from a 10" to a 16" barrel might increase velocity by 15%. Going from a 16" to a 20" barrel may increase velocity by just 3%."

    "Our increase in velocity jumps by 184 FPS, and when we go up one more inch (to 17"), we actually lose velocity! As we continue adding length to our barrel (from 17" up to 26"), we start to see more of those diminishing returns. Eventually, we gain just 11 and 19 FPS per extra inch of barrel. Small potatoes."

    For the majority of 556 owners I'd say 20 would suit them better. They won't benefit from a shorter barrel since the only time they'll use it is while they sit their ass at the range and not hit shit. The only benefit they can claim from a shorter barrel is blaming their own inaccuracies on it.

    No, 18" is. There's a big jump in FPS from 16 to 18, but not that big of a jump from 18 to 20. If anything 20" barrels don't make that much sense, especially considering you still get a rifle length gas system with an 18" barrel.

    Velocity is a huge consideration when shooting a round that depends on fragmentation to fuck its target up. The AR receiver is already so much shorter than say an AK or other comparable rifles, that the extra 2" of barrel doesn't even make it longer than a standard 16" barrel AK. You might as well get the extra inches and have all that extra velocity to fuck shit up downrange with, while not trying to squeeze more than it's worth like the 20" and above guys.

        You only care about dick size because you're mad you can still see yours after you tuck it.

      That's because girls don't actually get any satisfaction from penetrative sex. It doesn't feel like much either way to them. Pussys are designed to stretch and have very few never endings since they are used for something as traumatic as childbirth.
      All women basically feign satisfaction for the benefit of their partners.

        what is the point of the pistol brace if the grip makes it an AOW anyway?

          Could have stopped right there.
          The point is to adhere to arbitrary rules imposed by the ATF because there's no meaningful difference between an SBR and a 16" rifle but the fed needs to collect checks and have a background registry.

          It doesn't. That's only for vertical grips i.e. perpendicular to the bore. You can even put a BCM gunfighter grip on a pistol

    7" sbr with no suppressor is the new /arg/ meta. Who needs flashbangs when your gun shoots them?

    Saw your name, didn’t read what you wrote.
    Please strongly consider killing yourself, just not with a gun though.

    >I dont see much point in having a 5.56 gun shorter than 14.5" or longer than 18"
    You've come to a pretty reasonable conclusion.
    Now the next question is: why is 5.56 considered an appropriate cartridge for hunting coyotes when they weigh like, 20 pounds.

    No. Look at velocity and energy curves for barrel lengths on your favorite flavor of ammo and build your rifle around your use case with those metrics in mind.

    16" was the first AR I ever assembled and it's easily my best shooter.
