Description
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.
