The Rosco Manufacturing ROS-BCG-002 Bolt Carrier Group is a 5.56 NATO and 300 Blackout compatible BCG built to MIL Specification for the AR-15 platform. Constructed from stainless steel and finished in black phosphate, this full-auto rated carrier is designed to deliver the durability and corrosion resistance needed for high-round-count use.

Each ROS-BCG-002 is properly staked and features a chrome-lined gas key and bolt channel for smooth cycling, easier cleaning, and extended service life. The phosphate coating provides a tough, low-friction surface that stands up to demanding use, and every carrier is built to MIL-spec standards for reliable performance across pistol, carbine, and rifle length AR-15 builds.

Designed to meet the needs of the modern AR-15 shooter, the ROS-BCG-002 is a drop-in upgrade or replacement component backed by Rosco Manufacturing's commitment to quality and precision.
