[QUOTE="ARlife4me, post: 2698735, member: 105694"] Not all barrel mfgs are equal when it comes to gas system lengths. Aero Precision is the only 1 so far that is 100% good from the git go on standard rifle length gas. I have a cbi (criterion?) that has rifle length, but pops primers (I'll need to do some more adjusting). That barrel is a tac driver for sure! Proof barrels in SS and CF with +2 aren't near as good with function (needs more tuning). I have Faxon, 2A and 1 more brand (I'll get back to you) that's not near as good as the 1st 2. With AP I run standard weight buffer, spring and non-adjustable gb and it runs flawless! What I don't like is the 4.5-5# barrels, but now offer fluted that might save 6-8oz. Gas port size is very important as AP has it nailed! All of these have been tested with Hornady 120 a-max factory ammo. I also have 260rem barrels from PR also that has the same issue, but I'm working it out. Most have agb and vary on gas system length (standard to +2 rifle). Fixes will be a heavier buffer and maybe a stronger spring for better function. I also don't have or run any suppressors. [/QUOTE]
