Noveske Nitride Bolt Carrier Group BCG 5.56

The Noveske Rifleworks 5.56 M16 Bolt Carrier Group is a great option for building an AR-15 with reliability and ease of maintenance in mind. This BCG features the popular black Nitriding finish process that utilizes thermal chemical diffusion of Nitrogen and Carbon into the surface of the metal to physically change the properties. This process increases wear resistance, strength, corrosion resistance, and lubricity. Unlike the porous metal typical with phosphating, this surface is extremely smooth to prevent any kind of carbon buildup allowing for a smooth functioning rifle that doesn’t need to be oiled as much and can be wiped clean with a rag. Build a high-performance AR-15 today with the Noveske Bolt Carrier Group.
