[QUOTE="ARlife4me, post: 2703962, member: 105694"] I used to think the same thing, but it's not entirely true about headspace and chambers being that issue. I've found out that gas port size is the bigger issue! I know this by having several different manufacturers and gas system lengths in 6.5creed, 243win and 260rem. AP has been the only mfg with port size with standard rifle length system without an agb, standard recoil spring and buffer weight to run 100% without 0 issues from the start. Most of their barrels state port size and not all of their barrel lengths (same cartridge) are the same size. With the +2 gas it has taken a heavier buffer in PR barrels. It's not needed to have a 5+ oz buffer for 6.5creed, but might be required to function properly. [/QUOTE]
