I picked up the Faxon 11.5 and the SA gas block. with an H2 buffer and full mass carrier I couldn't get it to run 100% This rifle will be a suppressor host and will be used in competition. I swapped out the H2 for a JP SC spring with the lightest spring and a JP Low Mass BCG. I have only shot 100 rounds or so because I was getting ready for a match but it ran those rounds 100%
