installed my safety, changed buffer and shaved the high shelf lower BUT when in full semi auto, trigger will not compress as if it is in safety ... cant really find any solutions online. I have not shot it yet with the SS and its not lubricated just yet just due to the amount of times I've been taking it apart. (just wanted to leave that here just incase) please help!! Thanks in advance!!
(edit): the SS does not work even with the upper off.
