JP AR-10 / 308 High-Pressure Bolt Carrier Package

JP 308 High Pressure Enhanced Bolt Assembly Completion Group

This kit includes a bolt assembly, firing pin, cam pin, and retaining pin.
This version of the bolt is compatible exclusively with the JP LRP-07 and DPMS LR-308 platforms (or their clones) and cannot be used to replace bolts within the Armalite AR-10 platform (or its clones).

WARNING: The JP .308HP bolt does not accommodate the use of excessive pressure or overloaded ammunition that exceeds SAAMI specifications.
When trying new ammunition, always begin at the low- to mid-range of any published load data and gradually increase. A good indicator of working pressure is the retention of the primer during the subsequent loading of a case.
A noticeable loss of primer pocket tension suggests that your ammunition has excessive pressure and may have overworked the case.

Package includes bolt assembly, cam pin, firing pin, firing pin retaining pin, and instruction sheet.
