Thread: AR barrel configurations what do you run?

I've got (that I can think of)
In 223:
10.5" 1:7
14.5 M4 1:9
14.5 M4 1:7
16" Car Rifle Length Gas
16" Car Mid Length Gas
20" A2 HBar

18" 50 Beowulf Midgas 0.9"

16" M4 Pistol Gas 300 BLK

10.5" 9mm 0.7 Straight

12.5" 45ACP 0.74 Straight

24" 6mm Turbo 0.9


Anything longer than 18" and/or 0.8" is shithouse
1:7 will shoot anything you could possibly want

A shotgun should balance at the hinge pin, I believe there is a magic point for ARs to balance and bolt guns also..
Weight should be evenly distributed between the hands, and the balance changes with a loaded mag and scope fitted
