Alex Pro Firearms (APF) has been in business since 1976 crafting highly precise components. APF 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 APF Nickel Boron BCG is heat treated, shot peened, and machined to mil spec standards. If you are looking for a high quality BCG that will provide years of abuse, this nickel boron BCG is the perfect upgrade to your firearm.
