Hey all.
I received my AA 18in barrel upper an bolt the other day. Have it all together now the bolt won't engage the chamber. Could the barrel be to tight? I started @ 60 lbs then alined my gas block. On a prebuild all went together well then when I tightn it all up it seems to be hitting the top of the chamber. I already lossened the yh free float forarm. Is it posibble to tighten the barrel to tight? Any Ideas, it really has me scratching my head. No! I don't fleas . Thanks guys
