Attention to detail is what creates the highest quality products, and the new Black Nitride BCG is a perfect example of that. A case hardened 8620 steel carrier with an advanced low friction Black Nitride coating is the base for this BCG. 

We used a fully machine 4130 steel gas key instead of a MIM key like a majority of manufacturers, and then used grade 8 hardware with proper staking to attach it the a machined channel for proper locating and zero chance of movement. 

A case hardened 4340 cam pin holds in the shot peened, case hardened 9310, and Black Nitride coated bolt. The bolt is Mil-STD-1816 HPT and MPI tested and includes a crane O-ring on the shot peened case hardened 4340 steel Black Nitride coated extractor. A mil-spec firing pin made from centerless ground 8740 steel that is hard chrome, coated takes care of the primer ignition. Every single piece of this BCG went through a level of scrutiny that is rarely given in order to bring you the best BCG out there. Proudly made in the USA.
