JP Enterprises AR-10 Aluminum Variable Mass Operating System Bolt Carrier Group w/ .308 EnhancedBolt

JP EnterprisesA(R) AR-10 Aluminum Variable Mass Operating System Bolt Carrier Group w/ .308 EnhancedBolt features lightweight aluminum construction with a corrosion-resistant finish. This bolt carrier group (BCG) is designed for enhanced tunability of your system and helps ensure faster sight recovery for quick follow-up shots. Increased bearing surfaces create slower wear and longer lifespan while a longer Mil-Spec cocking pad ensures optimal reliability. The enhanced gas ring provides a perfect bore-to-gas seal fitment and minimizes friction and wear. Plus, the included titanium firing pin eliminates the possibility of slamfires. The bolt features SAE 9310 steel construction with corrosion-resistant DLC coating. A near frictionless surface provides smooth function while an enhanced ejector, extractor, and gas ring optimizes any setup. The EnhancedBolt(TM) is compatible with the JP LRP-07(TM) 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(TM) assembly, cam pin, firing pin, firing pin retainer pin and instruction sheet. The large-frame VMOS(TM) 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(TM) bolt carrier.
