ACME Machine has been in business since 1976 crafting highly precise components. All ACME BCG parts are of the highest quality and 100% made in America. ACME has taken their line of precision AR components and added a Nickel Boron coating to provide increased lubricity and much greater wear resistance than standard finishes. The ACME Nickel Boron BCG is heat treated, shot peened, MPI Tested, and machined to mil spec standards.
