FailZero has developed a series of unique bolt carrier groups that help reduce friction as well as provide smoother chambering of rounds, permanent dry lubricity and better protection against wear and corrosion. The EXO Nickel Boron series comes in a variety of styles and sizes to fit multiple setups, from M16 to AR15 to 7.62 x 39 and .308 Winchester. Each of these FailZero bolt carrier groups is made with the highest attention to quality, with added weight to increase reliability and performance, and quick, easy installation into most mil-spec upper receivers.
