The Umarex Komplete NCR – Nitrogen Cartridge Rifle – is the definitive stand-alone PCP air rifle. In .177 caliber, the Komplete uses a removable 12-shot auto-indexing rotary magazine. While the rifle does come with 2 magazines, there’s no reason why you shouldn’t stock up with more and this 2-pack is the right way to do that! This magazine is, like those that came with the rifle, super easy to load. Just insert the first pellet in through the loading port and rotate the magazine wheel around to the next open magazine slot. Keep loading airgun pellets until all spots are filled.
