Hey guys, I tried to remove the gas cylinder to shim it as the gas lock doesn't get tight until about 9 o'clock (and my groups are terrible). The problem is my barrel, which has been shortened, has an integral band around it it just behind the muzzle brake that is larger in diameter than the gas lock - so I can't remove the gas cylinder to get the shims in there.
Anyone have this problem and/or know how to get around it? I can't shorten the barrel anymore, maybe a machine shop could grind down the band??
Cheers.
