The commercially available action wrench system is uniquely designed to encircle and support the receiver ring and recoil lug, ensuring equal distribution of potentially damaging torque forces. The solid steel base features a specially machined relief to accommodate the recoil lug on most Mauser-type bolt action rifles. The individual, bolt-on heads are precisely machined to fit snugly around and against the receiver ring or barrel nut for each specified firearm model. This configuration supports the receiver with a steel ring, significantly increasing the gripping surface area to completely prevent twisted bolt ways or damaged receivers. This system represents the most advanced, comprehensive, professional-grade action wrench solution available. It effectively prevents costly receiver damage on most popular rifle actions, including military models, as well as selected handgun models. The two-piece head fully encircles cylindrical-style actions, ensuring 100% surface contact. The upper head indexes on the forward guard screw, correctly positioning the recoil lug during barrel installation. The system includes both heads and longer bolts, fitting all Remington actions with a receiver diameter of 1.355 inches. The double-angle design accommodates both factory lugs and Tubb and Shilen tapered designs.
