that frustration is the real mother of invention, someone there has found an easier way to reassemble the magazine. The Tandemkross Mag Tuner and Assembly Tool is actually a three-piece tool kit consisting of a synthetic cap nut tool, a synthetic reassembly assist tool and a standard 9/64 hex wrench. The kit comes in a zippered plastic pouch to keep the pieces together. An attached key ring and small carabiner permits attaching the pouch to whatever you want. With the Tandemkross kit, insert the reassembly assist tool through the front of the magazine body and drop the rotor onto it. Replace the back plate. Use the Tandemkross cap nut tool to hold the cap nut captive as you withdraw the reassembly assist tool from the magazine body. Turn the cap nut one and onethird turns (eight flats), then push the springloaded tool handle down to snap the cap nut down into its recess. Remove the tool then hold the cap nut in place with your thumb as you insert and tighten the cap nut screw. The rotor spring end fits into that tiny hole in the cap nut. Insert the Tandemkross reassembly assist tool. Here, the rotor stop contacts the feed lips assembly. SSUSA.ORG | DECEMBER 2020 33http://www.SSUSA.ORG
