JP Enterprises Enhanced Bolt Assembly Completion Group .308 Win, Black

Precision engineered bolt assembly for unmatched durability and performance Introducing our State-of-the-art bolt assembly, meticulously crafted from an ultra-strong SAE 9310 steel alloy, renowned for its exceptional durability and resilience. This advanced material, also utilized in the transmission gears of Formula 1 race cars, ensures that our bolt assembly outlasts standard carbon steel bolts by up to 10 times, significantly reducing the risk of failure during critical engagements. The SAE 9310 steel features a robust, ductile inner core that is highly resistant to stress fracturing, paired with a hardened outer surface that effectively combats galling and wear. This unique composition guarantees a remarkable service life of up to 60,000 rounds, making it the ideal choice for high-impact, high-heat applications such as sustained full-auto fire. Our bolt assembly is designed with precision machined radiuses on all 90 degree corners of the locking lugs, which evenly distribute impact forces to minimize premature wear and cracking. The fully supported extractor face and precise extractor engagement further enhance smooth and reliable cycling, ensuring consistent performance under demanding conditions. The "High Pressure" .308 Cal bolt variant features an improved extractor and a smaller diameter firing pin, specifically engineered to prevent primer flow in high-pressure loads. This entirely modified design enhances both strength and reliability, making it a superior choice for high-stress applications. Available individually or as part of a comprehensive completion group, our bolt assembly includes the bolt, firing pin, cam pin and firing pin retaining pin. Choose our precision engineered bolt assembly for unparalleled durability and performance in the most challenging environments.Constructed from SAE 9310 steel for enhanced durability and prolonged service lifeDLC coating offers exceptional surface hardness and lubricity while preserving a ductile coreSurface finish with minimal frictionFully compliant with military specification sub-componentsThe enlarged diameter of the cam pin hole significantly reduces the occurrence of common bolt failuresEnhanced lug geometry to minimize wear and facilitate smoother locking and unlockingThe enhanced ejector minimizes head case extrusions and decreases brass smearingThe enhanced extractor optimizes the extraction function and eliminates common ejection failuresThe enhanced gas ring minimizes internal friction and carrier wear while sustaining an almost indefinite gas seal
