Under 10” and Carbine length gas system I suppressed says H2 or H3, I would personally go with H3. I use H3 and Super 42 Spring on 8” Suppressed .300 AAC (Blackout) and have zero issues cycling. The suppressor is a HuxWrx Flow 762 Ti, so “not really suppressed” as far as back pressure is concerned.
