Description
JP Enterprises AR-10 Variable Mass Operating System H2 Bolt Carrier Group w/ .308 EnhancedBolt The EnhancedBoltâ„¢ is compatible with the JP LRP-07â„¢ 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). Requires DPMS-pattern bolt, firing pin and cam pin. Package includes carrier, EnhancedBoltâ„¢ assembly, cam pin, firing pin, firing pin retainer pin and instruction sheet. The large-frame VMOSâ„¢ 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 VMOSâ„¢ bolt carrier.
- Features (bolt carrier):
- Enhanced tunability of operating system
- Guaranteed reliability of difficult configurations
- Overcomes heavy fouling build-up
- Near total elimination of bolt bounce
- Roller-burnished bore for frictionless operation
- Rock-hard QPQ finish provides remarkable natural lubricity
- Extremely smooth cycling with proper lubrication
- Increased bearing surfaces for slower wear and longer component life
- Longer cocking pad for optimal reliability
- 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 reduced internal friction and carrier wear while maintaining near indefinite gas seal
- Reliable function with over-pressured loads such as 6.5mm and 6mm calibers (HP bolt)
- Virtually eliminates primer flow and pierced primes (HP bolt)
- Reduced firing pin mass improves lock time and ignition reliability (HP bolt)
