Barrel length

Made a post a while back about my findings with 556 barrel lengths and how they made no difference in POI at 350 yards in the shooting range. Have done more testing since then and can confirm that with all calibers and all weapons barrel length does not affect anything in terms of accuracy or velocity. Having a longer barrel simply hinders your ability to perform in cqb situations. Also tested some suppressors and they all sounded exactly the same to my ear, even the k (short) versions. Muzzle devices like the muzzle brake and different suppressors seemed to have no affect on recoil as well.
