Frequently Asked Questions

Will this fit a standard 5.56 AR-15 bolt? No, this firing pin is sized for AR-9 (9mm) bolts and is not interchangeable with a 5.56/.223 bolt carrier group.

What does the firing pin do? It strikes the cartridge primer when driven forward by the hammer, igniting the round.

Is gunsmithing required to install it? No special gunsmithing is required — it’s designed as a drop-in replacement for the factory firing pin.
