Lbe Ar Bolt Kit

The LBE AR Bolt Kit is a complete bolt carrier group component set designed for AR-15 rifle maintenance, repair, and rebuilds. Manufactured by LBE Unlimited and produced domestically in the USA, this bolt kit supplies the essential parts needed to assemble or service the bolt carrier assembly on modern pony-pinned AR platforms. For operators, gunsmiths, and serious enthusiasts managing inventory or performing field-level maintenance, having a dedicated bolt kit on hand eliminates downtime and ensures you maintain full operational capability without waiting for parts.

This kit includes four critical components: the 158 Carpenter Steel bolt, the firing pin, the cam pin, and the firing pin retaining pin—the exact parts that experience wear under cycling and require periodic replacement or backup inventory. The 158 Carpenter Steel specification is the mil-spec standard for AR-15 bolt material, selected for its hardness and resistance to peening under thousands of rounds of duty cycle. Each component is precision-manufactured to OEM tolerances, ensuring drop-in compatibility and reliable function when installed correctly. The modular approach allows you to replace individual worn parts or maintain a complete spare bolt assembly without purchasing full proprietary carrier units.

This product serves law enforcement armurers, military personnel, competitive shooters, and civilian operators who maintain their own weapons systems. Whether you're rebuilding a carrier that's seen significant round count, stocking spare parts for duty rifles, or performing maintenance between deployments, the LBE AR Bolt Kit provides USA-made components at a component-level price point. Compatibility is universal across AR-15 platforms using standard 7.62×51mm or 5.56×45mm bolt carriers, making this kit a practical addition to any tactical maintenance kit or gunsmith bench.
