nekshot,
from everything i've read so far, when i was building my 6.5Gr AR from parts, it seems most recommend a rifle length gas system if at all possible. now i assume you're going to drill a gas port? and if you're going to go to that effort and don't mind several trips on the drill press, i'd start with a very small hole. and it the rifle cycles, done. if not, open it up a few thousandths and try again.
the soviets did a 9x39 for their Spetsnaz teams using suppressed rifles. sounds like you're trying to re-create that. do a search on 9x39 and AR and see if anyone before has already been there, done that.
have fun,
