JP Low Mass Operating System Carrier Group with JP EnhancedBolt™ With High Pressure Bolt Assembly
   Large-Frame (.308)
   Stainless Steel
   Polished Finish

A low mass carrier provides the most significant improvement to felt recoil after the addition of a compensator. Our LMOS™ carriers remove much of the reciprocating mass out of the rifle's cycling. This translates into less felt recoil and less movement of the rifle. That means dramatically faster sight recovery and follow-up shots.

This carrier group includes our proprietary bolt design, the JP EnhancedBolt™. Superior in every way to standard bolts, it's manufactured from SAE 9310, providing drastically extended lifespan with design improvements that ensure superior function.

Our proprietary bolt design, the JP EnhancedBolt™ is superior in every way to a standard Mil-spec bolt. Manufactured from SAE 9310, it has a drastically extended lifespan while design improvements ensure superior function. This high pressure .308 model is designed to open up reliable function of AR platforms with over-pressured loads such as 6.5mm and 6mm calibers. This is achieved through use of a reduced diameter firing pin orifice that precisely accommodates the tip of the included low mass firing pin.

The EnhancedBolt™ 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).
