TandemKross Krossfire Bolt: Lightweight Performance Upgrade for Ruger Mark IV & 22/45
The TandemKross Krossfire Bolt for Ruger Mark IV & 22/45 with Halo (TK26N0540BWB1) is a premium complete bolt assembly designed to enhance the speed, reliability, and overall performance of the Ruger Mark IV and 22/45 pistols. TandemKross engineered this bolt with a lightweight skeletonized design that reduces reciprocating mass, resulting in faster cycling and smoother operation. This kit also includes the popular Halo charging ring, giving shooters both a performance bolt and an ergonomic charging solution in one package.
The factory bolt on the Ruger Mark series is functional but relatively heavy. By reducing weight through precision machining, the Krossfire Bolt allows the slide to cycle more efficiently. When combined with the included Halo charging ring, shooters gain a significant advantage in both speed and control. This upgrade is especially popular among competitive rimfire shooters who demand the fastest possible manipulation and most reliable function from their pistols.
