Phase5 Bolt Carrier Group M16 Blk

The Phase 5 Bolt Carrier Group M16 Black is a mil-spec complete bolt carrier assembly engineered to exacting military standards for reliable operation in AR-platform rifles. This HPT/MPI-tested unit delivers the durability and consistency demanded by operators, law enforcement, and precision shooters who depend on their weapons for critical applications. The assembly includes all necessary components: bolt, firing pin, cam pin, and gas key—ready for immediate installation.

Built with a heat-treated, chrome-lined interior and finished with black phosphate coating, this bolt carrier resists corrosion and thermal stress during sustained fire or field deployment. The chrome lining reduces friction and wear on the bolt face while extending service life under heavy use. Black phosphate provides a durable, low-reflective finish that meets mil-spec standards. Every bolt undergoes High Pressure Testing (HPT) and Magnetic Particle Inspection (MPI) to verify structural integrity and catch internal defects before they reach the field.

This bolt carrier is purpose-built for shooters who prioritize repeatability and longevity in M16 and M4 platforms. Rifle competitors, military personnel, and law enforcement units rely on mil-spec carriers during training cycles, duty rotations, and maintenance overhauls. The complete assembly eliminates guesswork on component compatibility and ensures proper function across standard AR-variant rifles.

Mil-spec bolt carriers represent the baseline reliability standard across the industry. Phase 5 Weapon Systems maintains tight manufacturing tolerances and verification protocols that exceed minimum requirements, making this carrier a trusted rebuild or upgrade component for serious shooters and professional users.
