Toolcraft AR15 Bolt Carrier Group Features MPI Magnetic Particle Inspected Carpenter 158 Steel Bolt with a 8620 M16 carrier. Because these Bcg's are one of the best in the industry, most top quality manufacturers source their bolt carrier groups from Toolcraft for this very reason. The Black Nitride coating vastly increases the hardness of the steel, prevents corrosion, is highly resistant to wear and heat. Bolt Heads are marked MPI C158 and are 100% made in the USA!!
