Compatible with any standard Mil-Spec upper! This bolt carrier is for any application where absolute reliability is the main criteria, the FMOS™ or Full Mass Operating System with 416 stainless steel special design carrier that includes forward assist serrations and a dust cover notch. The bore of the JP stainless carriers has a roller burnished finish for friction-less operation with no chance of peeling chrome as in standard mil-spec carriers. The exterior bearing surfaces are hand polished. When properly lubricated, both systems make your rifle feel like it was cycling on ball bearings.
The JPBC-2 carrier provides a 100% increase in bearing surface for smoother operation and improved alignment and lower wear in the upper receiver. AR-15 semi auto configuration in the rear with the mil-spec longer cocking pad in the front for best reliability. This is one of the best designed and highest quality general purpose carriers on the market. Sold as carrier with installed key. To completely install, you will need a complete bolt assembly, cam pin, firing pin and firing pin retainer.
