Any thoughts on a rifle length gas system for a 13.7 556 suppressed only. The dwell time with this setup is very close to my other blackout and 556 suppressed that run great and are quieter than the rifles with longer dwell times. I can open gas ports, adjust buffer weights & springs, bcg weight, agb, hammer spring tension etc etc. My only concern is suppressed. I'm already familiar with mid length 13.7 and run a carbine 10.3 suppressed and love it. Is the pressure reduction from mid length to rifle extreme? I realize that's only about an 1.5 to muzzle but there's another 6 plus inches of suppressor.
