Here are my specs for reliable cycling:
Cmmg 8.0" barrel
H2 buffer, standard m16 bcg (Mobil1 synthetic 5w-30 for lube)
AAC SDN-6 can
208 amax lc cut down brass
CCI 400 primer
Hodgdon Lil Gun 8.2 gr
2.135 oal with med crimp
1050 +-25 fps
**NOTE the gas port on the factory cmmg barrel is .093. This is not sufficient to cycle with this can/load/powder. I enlarged gas port to .109 (7/64 bit in drill press) to get 100% reliable cycling, and it does not overpressure the 110 gr Barnes factory loads.
Here's my 9mm subsonic load. Its stupid quite, light recoiling and very accurate.
Suarez RMR Match Slide
Lothar Walther Match Threaded Barrel
