My buddys DPMS 308 16" suppressed and even with a adjustable gas block turned all the way down it is still way over gassed. Even put a heavier buffer in there to try and tame it down.
Is yours a Carbine gas system?
There is a huge difference from his 16" carbine gas to the 18" rifle length i have on my AR10 on recoil. Mine is smooth and soft. His is like shooting a youth model 308 bolt action that only weighs 3#, Its brutal.
