Hey guys, I just completed my 80% lower Ar15 build and I absolutely love it. The only problem is it had started firing on the release of the trigger too. I am rocking the PSA MOE lower build kit, and have failed to replicate without live ammo, even through full function check. Once I get home imma make 100% sure my receiver is in spec. Could it just be the FCG? I know the springs aren't backwards
