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.
