The Umarex 40rd H&K MP7 Green Gas spare airsoft magazine by KWA is made from heavyweight aluminum, giving a hefty feel to the MP7 GBB 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. This is an Officially licensed replica with Heckler & Koch GmbH Trademarks! We recommend using Valken Green Gas with this gas pistol magazine.
