The ZK series is an experimental series of SMG's made by the Axle firearms corporation. Since it's experimental, it includes many new features, such as a blade on the bottom of the grip for close quarters combat, and a custom rail system. The ZK series of guns are still being tested out. The one in the picture is a ZK13, the thirteenth addition to the series.
