JP Enterprises AR-10 Variable Mass Operating System H2 Bolt Carrier Group w/ .308 EnhancedBolt 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). Requires DPMS-pattern bolt, firing pin and cam pin. Package includes carrier, EnhancedBolt™ assembly, cam pin, firing pin, firing pin retainer pin and instruction sheet. 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.

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)
