The UTG AR15 Mini Armorer’s Wrench (brand part number TLARWR02) is a compact steel multi-tool built by Leapers for installing and removing the parts AR-15 owners swap most often. It combines a castle and jam nut wrench, multiple torque wrench sockets, and several open wrench slots into one flat steel plate finished for wear resistance, so a single tool covers buffer tube nuts, muzzle devices, and other common fasteners without a drawer full of separate wrenches. A built-in flathead screwdriver rounds out the tool for small adjustment jobs at the bench. It’s a practical, no-frills addition to any AR-15 owner’s toolbox.
