JP AR10 FMOS BCG with HP Enhanced Bolt
JPBC-5AHP | Full Mass AR10 Bolt Carrier Group
JP AR10 FMOS BCG with HP Enhanced Bolt for any application where absolute reliability is needed. The 416 stainless steel Full Mass Operating System (FMOS) carrier design is the best of the best. The JPBC-5AHP has every strength an operator expects from a MIL-SPEC. carrier. Also, it is built upon improvements born from decades of shooting and engineering experience. Because the JPBC-5 is heavier than a standard .308 carrier, it is the solution for rifle needing more mass regulation.
Since it is designed with extended forward assist serrations and a dust cover notch, our FMOS™ carriers also feature a 100% increase in bearing surface for smoother operation. The improved alignment and lower wear in the upper receiver. The JP Full Mass BCG AR10 High Pressure Bolt Carrier Group has a longer MIL-SPEC. cocking pad for optimal reliability.
Surface and Finish
Just as critical as the design is the robust finishing process of the FMOS carrier. It receives a roller-burnish of its bore for frictionless operation. Because of this, it eliminates the peeling chrome common to standard Mil-spec carriers. Then, the exterior bearing surfaces are polished before the carrier undergoes our state-of-the-art, multi-vendor QPQ (Quench-Polish-Quench) process. This results in a rock-hard surface with great lubricity. This is hands-down the best designed and highest quality general purpose carrier on the market. Lastly, when properly lubricated, a JP operating system will make your rifle feel like it’s cycling on ball bearings.
