JP Enterprises AR-10 High Pressure Bolt Carrier Pin Package

This is the large frame (AR-10 / 308 AR) high pressure version of the JP Enterprises enhanced bolt carrier pin package. It contains JP's enhanced cam pin, a high pressure firing pin and a firing pin retainer pin. The cam pin is QPQ finished and machined thicker than typical undersized pins, and the retainer pin uses a cotter style design.

Read the fitment before you order. JP states the HP firing pin works only in JP High Pressure EnhancedBolt assemblies and should not go in any other bolt. The retainer pin fits DPMS LR-308 pattern carriers, not Armalite carriers. If you run a standard bolt, JP's regular 308 pin package is the one you need.
