We offer headspacing services with each bolt added to your AR barrel purchase. The JP high pressure bolts feature a smaller firing pin channel than standard DPMS pattern 308 AR bolts, minimizing primer pocket flow with higher pressure loads. This is beneficial for some of the hotter 6.5 Creedmoor factory loads available.
JP High Pressure EnhancedBolt™ Bolt Assembly
Caliber: .308 Win.
Finish: Black DLC
This bolt assembly is compatible with the JP LRP-07 and the DPMS Pattern 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.
