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.

Arm or Ally carries the JP Silent Captured Spring.  Also, check out our extensive AR Barrel inventory.  If you need more parts or looking to upgrade your AR15, view our full line of AR Parts.  We are America’s new AR parts headquarters.
