JP Enterprises .308 High Pressure EnhancedBolt Bolt Assembly
JP High Pressure EnhancedBolt™ Bolt Assembly
Caliber: .308 Win. caliber
Finish: Chromium Nitride
This bolt assembly 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). This bolt uses a specialized firing pin that is not compatible with other bolts nor can it use standard .308 firing pins.
WARNING: The JP .308HP bolt does not allow for the use of excessive pressure, overloaded ammunition that exceeds SAAMI specifications. When evaluating new ammunition, always start on the low- to mid-range of any published load data and work up. A good indicator of working pressure is the primer retention on the subsequent loading of a case. A noticeable loss of primer pocket tension indicates that your ammunition has excessive pressure and has overworked the case.
