The FailZero Bolt Carrier Group (FailZero part number FZ-AR10-01-NH) is a fully assembled DPMS-pattern .308 BCG finished in FailZero’s EXO Nickel Boron coating, ready to drop into most mil-spec AR10 upper receivers. The EXO Nickel Boron treatment provides permanent dry lubricity along with extreme durability, improving both wear resistance and corrosion resistance over an uncoated carrier. It is compatible with both .308 Winchester and 6.5 Creedmoor in a DPMS-pattern upper, and every major wear part is Nickel Boron treated rather than just the exterior housing, which is where a lot of cheaper coated BCGs cut corners.
