FailZero EXO Firing Pin – AR-15/M16

The FailZero EXO Firing Pin is a direct replacement for the standard AR-15/M16 firing pin, designed to reduce friction and improve reliability in adverse conditions. The EXO nickel boron coating provides a self-lubricating surface that resists carbon buildup and corrosion, making this firing pin particularly useful for high-volume shooters or those operating in dusty, wet, or low-maintenance environments.

Machined from hardened steel and finished with FailZero's proprietary EXO coating, this firing pin installs as a drop-in replacement with no gunsmithing required. The coating's low-friction properties mean easier cleaning and potentially smoother ignition cycles. Simply remove your bolt carrier group, replace the existing firing pin, and reassemble.
