FailZero AR-15 Bolt Carrier Group, EXO Nickel Boron Coated, Black Finish, No Hammer

The FailZero FZ-AR15-01-NH-BLACK is the black finish variant of FailZero's industry-leading EXO Nickel Boron Bolt Carrier Group, purpose-built for mil-spec AR-15 upper receivers chambered in 5.56x45mm NATO, .223 Remington, and .300 Blackout. Combining the proven performance of FailZero's patented EXO Nickel Boron internal coating with a tactical matte black exterior topcoat finish, this BCG delivers the best of both worlds: the unmatched dry lubricity and corrosion resistance of EXO NiB on every critical internal surface, with a low-glare black exterior appearance preferred by tactical and duty rifle builders.

The no-hammer configuration makes this BCG the ideal choice for complete builds and upgrades where the trigger group and hammer are sourced separately.
