JP Enterprises .308 High Pressure EnhancedBolt Bolt Assembly - Black

JP High Pressure EnhancedBolt Bolt Assembly - Black The High Pressure EnhancedBolt Bolt Assembly is made from 9310 steel and is expected to increase the life expectancy of your rifle for up to 10 years. This bolt features radiused corners, which strengthens the bolt, and allows it to handle high loads over a longer period of time than traditional bolts. 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. Caliber:.308 Win. caliber Finish:Chromium Nitride
