JP Full Mass Operating System Carrier Group with JP EnhancedBolt™
   .308 | .308 High Pressure
   Stainless Steel
   QPQ Black Finish

Their full mass .308 carrier is designed to provide greater reliability in suppressed setups as well as SBRs and rifles without an adjustable gas system. Heavier than a standard DPMS LR-308 carrier, the JPBC-5 allows for the additional cycling delay required for reliable function in such setups.

This design incorporates forward assist serrations, making it compatible with both DPMS and Armalite rifles. Each carrier also includes out Enhanced Gas Ring for more reliable function.

Requires DPMS-pattern bolt, firing pin and cam pin.

For a complete operating system, this carrier pairs best with the JPSCS2-10H2.

Compatible only with DPMS-pattern bolts, firing pin and cam pin.


Package Includes:

  • JP bolt carrier
  • JP EnhancedBolt (.308)
  • Cam pin
  • Firing pin
  • Firing pin retainer pin



WARNING:

The JP .308HP bolt does not allow for the use of excessive pressure, overloaded ammunition that exceeds SAAMI specifications. When evaluating new ammunition, always start on the low- to mid-range of any published load data and work up. A good indicator of working pressure is the primer retention on the subsequent loading of a case. A noticeable loss of primer pocket tension indicates that your ammunition has excessive pressure and has overworked the case.

 

Compatibility:

This notice pertains to any rifle based on the large-format AR-10-type or LR-308 platform typically chambered in .308 Winchester, 7.62x51 NATO or other cartridges requiring the longer magazine format.

Be aware that these receiver platforms are not standardized like the AR-15/M16 platform for which most parts are cross-compatible. Before ordering accessories and parts for your large-format rifle, make sure the parts are compatible with your particular platform. This bolt carrier group is compatible only with the DPMS family of AR-10 products.

With the Armalite family of large-frame receivers, this carrier can only be used as a complete bolt carrier assembly group with a DPMS-pattern bolt such as our .308 JP EnhancedBolt. Interchanging individual components will result in an unsafe configuration. Do not under any circumstances mix and match components between the platforms.
