GimmeLiberty 0 Posted March 8, 2009 Report Share Posted March 8, 2009 If you have a vodka special, try the King Armory gas piston and see if that solves your problems. Not too expensive and counts as 1 922 part. The first S12 I bought was a 2 holer, cycled nothing at all, but the dealer let me exchange it for the only other S12 in stock which happened to be a 3 holer. I brought that home and had the same issues. I did the gas port mod in the stickies and it helped, but I still had about 50% FTE's. I about gave up, but saw the KA gas piston looked different and gave it a shot. I have now gone from 50% FTE to 3% FTE (shoot 100 rounds of Federal Wally World ammo and had 3 fail to eject). I ran these cheapo rounds through a Surefire, an AGP and a ProMag and all cycled flawlessly. It does make a difference. Quote Link to post Share on other sites
