Aero Precision EPC 9mm AR-15 Bolt Carrier Group



Aero 9mm Bolt for EPC Receiver Sets

The EPC 9mm bolt from Aero Precision features excellent components for a reliable, durable AR-9 build. This 14.7-ounce bolt features an 8620 steel body with a grade 23 titanium firing pin. The purpose-built 9mm extractor reliably pulls casings out of the upper and is secured with a heavy-duty coil pin. Glock pattern magazines work perfectly with the cuts of the bolt.


Aero Precision recommends using mil-spec or PCC-specific trigger groups with this bolt for optimal reliability. Some standard aftermarket triggers may not be compatible. Additionally, this bolt cannot accept captured recoil springs like those from JP Enterprises or Armaspec.
