The Magpul Ranger floor-plate replacement for GI 30 round magazines incorporates an integral loop, floor-plate lock and magazine indentifier. The loop is made of pliable Sanoprene overmolded on a stainless steel plate. This speed-change magazine system is based on the paracord loop and tabs in use by special warfare units world-wide. The Magpul Ranger can also be installed on 20 round magazines with slight modification (trimming), but it is designed for current issue style 30 round magazines. Three pack includes three Ranger Plates and three floorplate loops.
