FailZero AR-10 Bolt Carrier Group (No Hammer) – Black EXO Coating

The FailZero AR-10 Bolt Carrier Group delivers reliable cycling in .308/7.62 NATO platforms with reduced friction and fouling buildup. This BCG features FailZero's proprietary EXO nickel boron coating applied to all contact surfaces, reducing the need for lubrication while maintaining consistent performance in adverse conditions. The "no hammer" designation means this carrier is designed for AR-10 pattern rifles that use a separate fire control group—verify compatibility with your specific lower receiver before installation.

Constructed from mil-spec 8620 steel (carrier) and 9310 steel (bolt), this BCG is finished in black EXO coating for corrosion resistance and easy cleanup. Installation is drop-in for compatible AR-10 rifles with standard .308 bolt dimensions. The coating's self-lubricating properties extend time between cleanings, though FailZero recommends light lubrication for initial break-in and long-term storage.
