The Barrier Defense Bolt Carrier Group includes a complete 7.62x39mm NATO bolt assembly, mil-spec (M16-type) bolt carrier, firing pin, cam pin, and staked gas key. The high quality bolt carrier is precision machined from ordnance-grade 4130 chrome moly steel, while the bolt is constructed of high strength 8620 steel. Other than the stainless steel firing pin, the entire bolt carrier assembly features a black manganese phosphate coating for superior corrosion resistance and durability. Due to limited supply and industry wide shortage, this price will not last so make sure to pick one up for your next rifle build or for use as a spare before it's too late!
