Our new Reduced Friction Black Nitride BCG w/Logo utilizes strategically located bearing surfaces to reduce carrier contact and friction. By adding in machined lubrication channels and surfaces in addition to the minimal bearing surfaces, reliability is increased immensely.
A slight increase in weight also ensures proper dwell time and extraction. 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 milspec firing pin made from centerless ground 8740 steel that is hard chrome coated, takes care of the primer ignition.
