JP Enterprises AR-15 Enhanced Bolt Carrier Pin Package

The JP Enterprises enhanced bolt carrier pin package for small frame AR-15 rifles holds JP's enhanced cam pin, firing pin and firing pin retainer pin. These are the pins JP puts in its own rifles and upper builds.

JP machines the cam pin thicker than the usual undersized pin and gives it a low friction QPQ finish, which cuts the slop that stresses the cam pin hole in the bolt. All three keep mil-spec critical dimensions, so they drop into a standard AR-15 carrier with no proprietary parts.
