Faxon Firearms Complete Bolt 5.56x45mm, Black

At Sons of Liberty Gun Works, MIL-SPEC is just the starting point. We push beyond the standard to deliver the best options for our demanding customers. Our bolt is crafted from 9310 tool steel, a superior material that offers enhanced strength and durability. The entire assembly is nitride, improving surface hardness, reducing friction, and providing superior corrosion resistance compared to traditional phosphate bolts. Every bolt undergoes full MPI testing to ensure it is free from material defects. To enhance reliability, bolt lugs are chamfered at a 45 deg angle, allowing for smooth operation even with high-pressure hand loads and fast, lightweight actions. The extractor is precision-machined from S7 tool steel and equipped with a premium spring, O-ring, and silicone insert for optimal performance. Built for reliability and longevity, this bolt assembly is engineered to exceed expectations. 9310 tool steel construction bolt, designed for exceptional strength, wear resistance and long lasting performance Full Mil-Spec heat treatment bolt, ensuring durability and performance under high stress conditions Shot-peened to Mil-Spec bolt, ensuring high-quality durability and performance Magnetic particle inspection (MPI) bolt, providing an added layer of reliability by inspecting for cracks or defects Back of lugs chamfered for reliability, improving the bolt's operation by reducing wear and ensuring smoother cycling Spring, insert and "crane" O-ring Installed bolt, ensuring smooth and reliable operation of the firearm Salt bath nitride bolt, improving durability and resistance to wear S7 tool steel construction extractor, ensuring superior strength and reliability for extraction performance Fully heat-treated extractor for enhanced durability and reliability in extracting rounds Shot-peened per Mil-Spec extractor, improving extractor strength and durability through shot peening
