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.

Primary Arms and JP enterprises came through!
by RB National Ltd.Co. -
As everyone knows, when you need the best parts in the business you go to the best place to get em. That’s what happened. The .308 bolt fit perfectly in my JP enterprises low mass stripped bolt carrier. My .308 kicks less than my 6.5 Grendel now and weighs 8lbs 8oz. Difference is unreal. Highly recommend to anyone working on a long distance AR10 and wanting to be able to see impacts or someone needing to make quick follow up shots. I also use the precision armament m4-72 muzzle brake and the gun doesn’t move at all when fired, even on a bog death grip tripod it’s so still you can easily see your bullet impacts and adjust accordingly.
Works great
