TandemKross KrossFire Bolt Features The TandemKross KrossFire Bolt is machined from heat-treated billet steel and fitted with a lateral retaining pin that prevents the firing pin from moving vertically so it only travels forward and back as intended. This precise control over firing pin movement delivers more consistently positive primer strikes reducing the chance of a light strike or failure to fire. The bolt ships with TandemKross s Fire Starter titanium firing pin pre-installed which is both highly durable and lighter than a steel pin helping reduce lock time and allow for faster consecutive shots on target. Precisely machined and radiused surfaces promote smooth movement and consistent hammer engagement throughout the cycle. A long-lasting bolt deserves long-lasting parts so the KrossFire also comes with TandemKross s hardened tool steel Eagle s Talon extractor pre-installed which is highly resistant to wear and aggressively hooked to confidently secure cartridges and reduce failures to extract. The bolt s black PVD coating offers more than just a good-looking finish providing a protective layer that helps the precisely machined components keep running as long as possible. Weighing just 0.65 ounces the KrossFire Bolt is a direct drop-in upgrade for the Ruger 10/22 platform. Made in the USA it is built for shooters seeking improved reliability and performance from their rimfire rifle.
