FailZero 9mm Bolt Carrier Group (No Hammer) – Black Nitride Finish

The FailZero 9mm Bolt Carrier Group is engineered for blowback-operated 9mm AR-pattern pistols and carbines. This hammerless design is compatible with firearms that do not require a traditional hammer interface, streamlining the BCG profile for reliable cycling in dedicated 9mm platforms. FailZero's proprietary EXO coating over black nitride ensures consistent performance with reduced friction and fouling buildup.

Constructed from mil-spec steel with black nitride treatment, this BCG features FailZero's nickel boron EXO coating on critical wear surfaces. The coating provides self-lubricating properties and corrosion resistance. This is a drop-in component for compatible 9mm AR lowers, though proper headspacing and function testing are required after installation. Includes bolt, carrier, cam pin, and firing pin.
