This is a URX wrench built for the KAC SR15 barrel nut. We found this barrel wrench when looking for a solution to remove a very tough barrel nut, and we were at the point of breaking the wrench we had or stripping the teeth off the nut. Made in America by a small machine shop. Our friends at Potomac Armory have sourced this wrench for us, and we swear by it.
Made by a small business called Classified Defense. While Charlie's is not a tool shop, we do like to feature unique tools that we use in our workshop. We especially like featuring made in America small business innovation.
This wrench is an upgrade to the Knights factory wrench. Made from 304 Stainless Steel
To use, be sure to remove the gas block and muzzle device first. We recommend the use of Locktite #242 (blue) when installing, and lots of elbow grease when uninstalling. A torque wrench is recommended at 55 ft-lbs.
