RCA 5.56 Black Nitride Bolt Carrier Group M16
Noveske marked with a black nitride finish. Carrier features 8620 steel with 158 Carpenter Steel bolt and 9310 tool steel extractor and cam pin.
Much more than typical Parkerizing, phosphating or black oxide, Blacknitriding is a thermal chemical diffusion of nitrogen and carbon into the surface of the steel. This process increases wear-resistance, fatigue strength, corrosion resistance, lubricity and cosmetic appeal.
