The Umarex H&K USP Co2 18rd spare airsoft magazine by KWC is made from heavyweight aluminum, giving a hefty feel to the USP airsoft pistol. This green gas Umarex magazine has a high-efficiency internal gas system providing excellent FPS output, and reinforced valves and seals for optimal gas retention.
