DESCRIPTION
I'd have to tear the bolt apart and measure the firing pin, but in a nut shell, the tail end of it has been relocated to be more shrouded by the BCG. Our basic testing showed the original bolt is capable of firing with a broken neck in the chamber. Revised bolt will not, but since there's no additional safety measures there's always a chance. :D This is probably one of more favorite hosts when shooting 5.7 suppressed since the gases get directed down. I need to experiment with heavier buffers and subs. AR57 Upper: https://alnk.to/2Qx3JPh
