JP Enterprises LMOS Bolt Carrier Group 223 EnhancedBolt Stainless Polished Low Mass AR-15 BCG

JP Enterprises LMOS Bolt Carrier Group with EnhancedBolt.223 AR-15 A Low Mass Carrier A Polished Stainless EnhancedBolt A SAE 9310 A Enhanced Ejector / Extractor / Gas Ring A 8.8 oz The JP Enterprises LMOS BCG is a low mass bolt carrier group for .223 AR-15 platforms. Low mass carrier removes reciprocating mass from the rifle's cycling for reduced felt recoil and faster sight recovery. High polish finish on roller-burnished bore. Carrier design prevents dust cover from closing when rifle is not fully in battery. Includes JP EnhancedBolt-polished stainless SAE 9310 steel bolt with enhanced ejector, extractor, and gas ring. Increased diameter cam pin hole eliminates the most common bolt breakages. Improved lug geometry reduces wear and eases locking/unlocking. Enhanced gas ring reduces internal friction while maintaining gas seal. Package includes carrier, bolt assembly, cam pin, firing pin, firing pin retainer pin, and instruction sheet. 8.8 oz. Not for use in .308 AR-type rifles.Low Mass CarrierLMOS design removes reciprocating mass for reduced felt recoil and less rifle movement. Roller-burnished bore and high polish finish for smooth cycling with proper lubrication. Increased bearing surfaces reduce wear. Longer mil-spec cocking pad for optimal reliability.EnhancedBolt - Polished Stainless SAE 9310SAE 9310 steel bolt with polished stainless finish provides superior resiliency and extended lifespan over standard mil-spec bolts. Near-frictionless surface finish. Fully compatible with mil-spec sub-components.Increased Cam Pin Hole DiameterIncreased diameter cam pin hole eliminates the most common bolt breakage point. Improved lug geometry reduces wear and eases locking and unlocking under sustained fire.Enhanced EjectorEnhanced ejector mitigates head case extrusions and reduces brass smear. The improved geometry addresses common ejection failure modes in standard mil-spec bolts.Enhanced ExtractorEnhanced extractor optimizes extraction function and eliminates common ejection failures. The improved extractor geometry maintains positive case extraction across varied ammunition types.Enhanced Gas RingEnhanced gas ring reduces internal friction and carrier wear while maintaining a near-indefinite gas seal. The improved ring geometry extends component life over standard mil-spec gas rings.Not for .308Not for use in .308 AR-type rifles. Compatible with .223/5.56 AR-15 platforms using mil-spec bolt carrier and sub-components.Package ContentsIncludes carrier, bolt assembly, cam pin, firing pin, firing pin retainer pin, and instruction sheet. The JP LMOS BCG delivers low mass AR-15 cycling performance-polished stainless EnhancedBolt with SAE 9310 steel and enhanced ejector, extractor, and gas ring for reduced recoil and extended component life.Specifications:Manufacturer: JP EnterprisesModel: LMOS Bolt Carrier Group with EnhancedBoltCaliber: .223 / 5.56 AR-15Carrier Type: Low Mass (LMOS)Carrier Finish: High Polish (Roller-Burnished Bore)Bolt Material: SAE 9310 Stainless SteelBolt Finish: Polished StainlessEjector: EnhancedExtractor: EnhancedGas Ring: EnhancedCam Pin Hole: Increased DiameterLug Geometry: ImprovedMil-spec Compatible: YesWeight: 8.8 ozIncluded: Carrier, Bolt Assembly, Cam Pin, Firing Pin, Firing Pin Retainer Pin, Instruction SheetNot Compatible With: .308 AR-Type Rifles
