JPBC-8 BCG

Like our small-frame JPBC-1, this carrier is the ultimate game gun operating system, now available for your heavy metal rig. The JPBC-8 offers an extremely light recoil impulse with minimal sacrifice in reliability.

The JPBC-8 also pulls from the advances of our JPBC-7 VMOS™ carrier. This standard version of the aluminum large-frame VMOS carrier includes three steel weights, two of which can be exchanged for heavier tungsten weights.

This carrier group includes our proprietary bolt design, the JP EnhancedBolt™. Superior in every way to standard bolts, it's manufactured from SAE 9310, providing drastically extended lifespan with design improvements that ensure superior function.

The EnhancedBolt™ is compatible with the JP LRP-07™ and the DPMS LR-308 platforms (or clones thereof) only and cannot be used to replace bolts in the Armalite AR-10 platform (or clones thereof).

Package includes carrier, bolt assembly, cam pin, titanium firing pin, firing pin retainer pin and instruction sheet.

Weight: 10.1 oz.

Features (bolt carrier):

• Enhanced tunability of operating system
• Faster sight recovery and follow-up shots
• Increased bearing surfaces for slower wear and longer component life
• Longer Mil-spec cocking pad for optimal reliability
• Included Enhanced Gas Ring provides perfect bore-to-gas seal fitment and minimized friction/carrier wear
• Included titanium firing pin eliminates possibility of slamfires at higher bolt velocities
• Full-length forward assist serrations

Features (bolt):

• SAE 9310 steel construction for superior resiliency and extended lifespan
• DLC coating provides extreme surface hardness and lubricity while maintaining a ductile core
• Near frictionless surface finish
• Fully compatible with Mil-spec sub-components
• Improved lug geometry for reduced wear and easier locking/unlocking
• Enhanced Ejector mitigates head case extrusions and reduces brass smear
• Enhanced Extractor optimizes extraction function and eliminates common ejection failures
• Enhanced Gas Ring reduces internal friction and carrier wear while maintaining near indefinite gas seal

Compatibility:

• The large-frame VMOS™ carrier uses the same steel and tungsten weights as GEN 2 Silent Captured Spring units. Only the forward two masses are reconfigurable. The rear-most steel mass cannot be exchanged. This carrier should not be run stripped (i.e., without any masses).
• This carrier will not cycle with a standard buffer retainer plunger installed and should be used only with a Silent Captured Spring.
• Because our Law Tactical Folder Silent Captured Springs require use of a buffer retainer plunger to work, they are also not compatible with this VMOS™ bolt carrier.

Recommendations:

This carrier is not recommended for use with gas systems shorter than mid-length for longest service life. Use with carbine or shorter gas systems may result in gas erosion in the tail stock area and subsequent leakage and reduced service life.

To help avoid the instance of slamfires, this bolt carrier comes packaged with a titanium firing pin. We strong encourage use of a titanium firing pin with this carrier to ensure safety.

Use of a hammer with a radiused leading edge such as our JP Speed Hammer is recommended.

Use with a Silent Captured Spring assembled with a lighter weight spring will produce superior results.
