JP Enterprises JPBC-3A LMOS Low Mass Bolt Carrier Group 5.56 QPQ Black

A low mass carrier provides the most significant improvement to felt recoil after the addition of a compensator. Our LMOS(TM) 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(TM). Superior in every way to a standard Mil-spec bolt, it's manufactured from SAE 9310, providing drastically extended lifespan with design improvements that ensure superior function.The EnhancedBolt(TM) is compatible with any AR-15 platform using a Mil-spec bolt carrier and sub-components.Package includes carrier, bolt assembly, cam pin, firing pin, firing pin retainer pin and instruction sheet.Not for use in .308 AR-type rifles.Features (bolt carrier): Design prevents dust cover from closing when rifle not fully in batteryRoller-burnished bore for frictionless operationRock-hard QPQ finish provides remarkable natural lubricityExtremely smooth cycling with proper lubricationIncreased bearing surfaces for slower wear and longer component lifeLonger Mil-spec cocking pad for optimal reliabilityFeatures (bolt): SAE 9310 steel construction for superior resiliency and extended lifespanDLC coating provides extreme surface hardness and lubricity while maintaining a ductile coreNear frictionless surface finishFully compatible with Mil-spec sub-componentsIncreased diameter cam pin hole eliminates most common bolt breakagesImproved lug geometry for reduced wear and easier locking/unlockingEnhanced Ejector mitigates head case extrusions and reduces brass smearEnhanced Extractor optimizes extraction function and eliminates common ejection failuresEnhanced Gas Ring reduces internal friction and carrier wear while maintaining near indefinite gas sealWeight: 8.8 oz.
