CYMA 570rnd Dual Clamp High-Cap Magazines for SMG-5 AEGs

This high capacity magazine is designed for SMG-5 AEGs and holds a whopping 570rnds, much more than any other SMG-5 magazines. It is filled from the top of either magazine by pulling back the mock bullets or opening the fill window, and wound from the bottom clockwork wheel to feed BBs.
