My 12.5" Centurion runs great with an A5H3 + BCM rifle spring. I do think my gas port is slightly smaller than the BCM barrel though (mine measured out around .065", I believe).

Ok thanks much for all the responses...I have the standard Spikes buffer in there that came with the lower. It seems pretty "snappy" when running suppressed, so thats the main reason I was wondering.
