JP 9mm AR Bolt with Silent Captured Spring JPBC-9MM-SCS2

JPBC-9MMA-SCS2 | 9mm AR Bolt Carrier Group w/ Silent Captured Spring

JP Enhanced 9mm AR Bolt is machined to the same exacting tolerances as JP bolt carriers.  However, this second generation 9mm bolt assembly is an entirely new design.  It eliminates the need for a central mass (slug) to readily function with the JP 9mm Silent Captured Spring.  All of this without compromising bolt weight and reliability.  In fact, this package has the heaviest, most reliable 9mm operating system.  Because of these features, it reduces bolt bounce while improving accuracy.

JP Enhanced 9mm AR Bolt is .9 oz. heavier than the Rock River Arms 9mm bolt with its central mass removed.  This complete 9mm operating system is slightly heavier than the complete RRA bolt and buffer.  Keep in mind, some of the bolt mass having been transferred to the SCS in our system.

Arm or Ally carries an extensive 9mm AR Barrel inventory.  If you need more parts or looking to upgrade your AR15, view our full line of AR Parts.

Use of this bolt requires a 9mm Silent Captured Spring or 9mm buffer and spring. It will not function with standard AR-15 buffer components. The JPBC-9MMA is compatible with both Colt SMG-style magazines and Glock pistol magazines. The JPBC-9MMA is also compatible with our JP side-charging uppers.
