The LMT Defense Full-Auto Enhanced 5.56mm Bolt And Bolt Carrier Group Black is engineered for shooters who demand dependable cycling from their AR-15 platform. Built around an M16-style carrier and a proprietary 5.56x45 NATO bolt, this enhanced group is optimized for full-auto, suppressed, and short-barrel setups, using materials and geometry that go beyond standard mil-spec components to improve extraction and gas management.

This bolt carrier group is ideal for high-volume range sessions, training, and duty-style rifles where consistent function and easier maintenance matter. Its revised cam path, gas porting, and extractor design help keep the rifle running smoothly under hard use while reducing gas blowback toward the shooter. Backed by LMT Defense’s reputation for precision machining and thoughtful engineering, it offers a refined upgrade for serious AR-15 builds.
