TandemKross Krossfire Bolt for Ruger Mark IV & 22/45 .22 LR - Black

The TandemKross Krossfire Bolt is a precision drop-in replacement bolt assembly engineered for the Ruger Mark IV and Mark IV 22/45 pistols chambered in .22 LR. CNC machined from hardened steel, the bolt body is finished in a wear- and corrosion-resistant black DLC (Diamond-Like Coating) that reduces friction, minimizes wear, and extends service life under high round counts.

This complete bolt ships fully assembled with TandemKross performance internals already installed and retained, including the TandemKross firing pin, extractor, and guide rod. The bolt also features an integral Halo charging ring that gives the slide a larger, easier-to-grab charging surface for faster and more reliable manipulations.

Drop it into your Ruger Mark IV or 22/45 pistol and you're ready to run - no fitting or extra parts required.
