JP Enterprises High Pressure .308 Bolt Assembly with Custom Firing Pin - DPMS Pattern
Details
The JP Enterprises JPEB-308HP EnhancedBolt™ Assembly is built for large-frame AR rifles that run .308 Winchester and similar calibers. Machined from premium SAE 9310 steel with a DLC finish, this high pressure bolt assembly offers exceptional durability and consistent performance where standard bolts fall short. Designed specifically for DPMS LR-308 and JP LRP-07 style platforms, the reduced firing pin orifice and optimized low mass firing pin help minimize primer flow and improve ignition reliability.
Every component is engineered to handle a wider range of higher pressure SAAMI-compliant ammunition loads while resisting wear and stress with a near frictionless surface finish that makes cycling smooth and reliable under tough conditions. This is a solid upgrade for anyone seeking a long-lasting, precision-minded bolt assembly that keeps your rifle operating reliably shot after shot.
