I currently have a Spikes Tactical ar15 in .223 (non piston). I have a Silencerco Saker .556 can on it. I can shoot 1-3 rounds before it has a FTE or jams. I'm shooting PMC Bronze 55 grain. I really don't want to change ammo because I have a ton of it... But as soon as I pull the suppressor off the gun functions flawlessly. Do I really need to go to a piston upper with an adjustable gas block or a self regulating system. Any suggestions?
