Featuring a full metal build, this reliable 40-round magazine is more than just a spare. Its extended design allows users to double their ammo capacity (smaller versions only hold up to 20 rounds) when using KWA's highly sought-after gas blowback MP7 submachine gun. This extended magazine fits and feeds perfectly into the the MP7, licensed by Heckler & Koch, and features an extremely high quality construction. Equipped with an advanced gas seal system to prevent leakage, this extended magazine completes the package, not to mention that it adds the distinct long mag configuration every gas blowback MP7 should sport.
