JP AR15 FMOS Full Auto BCG with JP Enhanced Bolt
JPBC-16A | Full Mass & Full Auto AR15 Bolt Carrier Group
JP AR15 FMOS Full Auto BCG with JP Enhanced Bolt is 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-16A has every strength an operator expects from a Full Auto MIL-SPEC carrier group.

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.

Be aware that it is inadvisable to use any full auto components in an AR-15 semi-auto rifle. If you happen to have an unexplained "double" (more than one round firing with one press of the trigger), you could be prosecuted for manufacturing and possessing an illegal weapon.
