[QUOTE="ARlife4me, post: 2865714, member: 105694"] Another thing is that gas travels slower than bullets down a barrel (on most occasions). So next question will be...................on barrels longer than +2 (appx 14.7" not counting inside the receiver) should a 26" + length barrel meets half the distance of gas port and muzzle? Or does it matter that much? I'm seeing offerings of up to 28" on an AR barrel. I do have a factory rock river 308win w/26" barrel, but haven't checked if it's Armalite length? It might be as the bcg is longer than dpms? No issues with the gun, just questioning? [/QUOTE]
