BCM Bolt Carrier Group MPI Auto - FDE IonBond

Bravo Company Manufacturing's FDE IonBond bolt carrier group represents the company's commitment to duty-grade reliability with premium surface treatment. The carrier is machined to USGI specifications with a chrome-lined interior and uses an FDE IonBond finish for corrosion resistance and easier cleanup than standard phosphate.

The IonBond finish resists carbon buildup better than standard finishes, and what carbon does accumulate wipes away more easily during cleaning. The chrome-lined carrier interior and heat-treated gas key secured with Grade 8 fasteners and proper staking ensure long-term durability under high round counts.

BCM's bolt assembly uses Carpenter No. 158 steel that has been shot peened for increased strength, then subjected to both high pressure testing (HPT) and magnetic particle inspection (MPI). The enhanced extractor provides improved reliability with various ammunition types. This BCG is built to the same specifications as those supplied to military and law enforcement agencies, making it an excellent choice for serious duty use, home defense, or demanding training schedules.
