Bravo Company Bolt Carrier Group (MPI) – Auto

The Bravo Company Bolt Carrier Group (MPI) – Auto is built to exacting military specifications and is a top-tier component for AR-pattern rifles. Designed for reliability in both semi-automatic and full-automatic operation, this complete BCG is constructed using Carpenter No. 158® steel, ensuring long-term durability in high-round count environments. The carrier is parkerized on the exterior to guard against corrosion and wear, while the interior is chrome-lined for improved smoothness and resistance to fouling during extended use.

This BCG is fully assembled and features a Magnetic Particle Inspected (MPI) bolt that is shot-peened and High Pressure Tested (HPT) for critical stress resistance. The gas key is chrome-lined, heat-treated per USGI standards, and secured with Grade 8 fasteners that are properly staked to prevent any loosening during extended fire cycles. These features provide a dependable seal and consistent gas flow for flawless cycling in any condition.

The Bravo Company BCG is compatible with standard AR-15 platforms chambered in 5.56 NATO, .223 Remington, and .300 AAC Blackout. It may also be used in properly configured rifles chambered in .224 Valkyrie, 6.8 SPC, and 7.62x39mm, though caliber-specific bolts are required for those cartridges due to different case head dimensions. Regardless of configuration, BCM’s commitment to performance makes this BCG a trusted upgrade for tactical applications, duty rifles, and high-end personal builds.

Each unit is precision-machined to USGI specifications and offers drop-in compatibility with most AR-15 upper receivers. The result is consistent lockup, reliable extraction, and smooth chambering, whether you’re running suppressed setups or match-grade ammo.

Backed by Bravo Company’s lifetime workmanship warranty, the BCM MPI Auto BCG is a battle-proven component designed for serious shooters.
