Faxon Firearms FF-22 Rimfire 10/22 Bolt Assembly - Black Nitride

The Faxon Firearms FF-22 Rimfire Bolt Assembly is a drop-in replacement bolt for the Ruger 10/22 semi-automatic .22 LR rimfire rifle. CNC-machined from 17-4 PH billet stainless steel and finished in black nitride, this bolt is built to deliver long service life and reliable cycling in a rimfire action that runs hard and dirty.

Each bolt ships fully assembled and ready to install, with an extractor and a hardened firing pin already fitted. The 17-4 PH stainless steel is heat-treated to H900 condition for an HRC 40 hardness, providing the wear resistance and dimensional stability needed to cycle rimfire ammunition consistently. The black nitride surface treatment reduces friction, resists corrosion, and offers a low-glare finish suited for field use.

Designed as a direct replacement for the factory Ruger 10/22 bolt, this assembly is also fully compatible with the Faxon FF-22 receiver, making it an ideal upgrade or spare for any 10/22-pattern rimfire build. Whether you are replacing a worn factory bolt or assembling a custom 10/22, the FF-22 rimfire bolt assembly delivers a precision-machined, drop-in component built for the long haul.
