FailZero combines quality mil-spec components with a high-performance NiB coating to create some of the finest AR parts on the market. Their 6mm ARC bolt carrier group is the perfect example of FailZero production and will make an excellent addition to your next AR-15 build. It ships fully assembled and is ready to drop in without needing any additional parts. Unlike typical mil-spec units the critical components of this bolt carrier group have been EXO Nickel Boron coated for increased wear resistance, enhanced durability, and permanent dry lubricity. This attractive coating results in overall smoother operation of the weapon while reducing unnecessary malfunctions. No 6mm ARC build is complete without an American made FailZero bolt carrier group.
