Description
JP Low Mass Operating System Carrier Group with JP HP Bolt
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.
Weight: 14.25 oz.
Package Includes:
- JP bolt carrier
- JP HP Bolt (.308)
- Cam pin
- Firing pin
- Firing pin retainer pin
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.
Compatibility:
This notice pertains to any rifle based on the large-format AR-10-type or LR-308 platform typically chambered in .308 Winchester, 7.62×51 NATO or other cartridges requiring the longer magazine format.
Be aware that these receiver platforms are not standardized like the AR-15/M16 platform for which most parts are cross-compatible. Before ordering accessories and parts for your large-format rifle, make sure the parts are compatible with your particular platform. This bolt carrier group is compatible only with the DPMS family of AR-10 products.
With the Armalite family of large-frame receivers, this carrier can only be used as a complete bolt carrier assembly group with a DPMS-pattern bolt such as our .308 JP EnhancedBolt. Interchanging individual components will result in an unsafe configuration. Do not under any circumstances mix and match components between the platforms.
