The Aero Precision EPC/AR9 Bolt is the core of your EPC build. Machined from 8620 steel and featuring a nitride finish, fracture resistant grade 23 titanium pin, and 4140 steel extractor, the EPC bolt assembly is precision machined from the ground up to meet the extreme demands of blowback AR platform firearms.
Disclaimer:Â Our 9mm Bolt may not be compatible with some aftermarket fire control groups. It is recommended to use a mil-spec or PCC specific trigger group. After assembly, verify proper operation and trigger reset with an unloaded firearm prior to use.
This bolt is not compatible with most AR15 folding stock adapters.
