Overview

The LanTac Enhanced M16 Bolt Carrier Group is precision-machined for .223 Remington and 5.56x45mm NATO AR-platform firearms. The carrier is crafted from 8620 steel and features a shot-peened Carpenter 158 steel bolt that undergoes magnetic particle inspection (MPI). The entire assembly is coated with a proprietary UCT EXO Electroless Nickel Boron process, delivering a surface hardness of 82-85 Rockwell C and an extreme friction coefficient of .02 for enhanced lubricity, cooler and cleaner operation, and reduced upper receiver pressurization when shooting suppressed. The carrier incorporates a patent-pending forward-porting gas vent design, a balanced flared tail boss for consistent lock-up and improved accuracy, a hard chrome-lined bore and gas key, a properly staked gas key with grade 8 fasteners, and a patent-pending CP-R360 domed cam pin machined from 17-4PH stainless steel.
