A very quick presentation by Gunfire on the KWA Ronin TK.45C 2.5 AEG... "When designing the Ronin TK.45 2.5 model, KWA attempted to create a replica of a submachine gun powered by pistol-style magazines. The gun is made of metal elements and durable polymer. In this version, the replica has a PDW stock, a quick spring change system, and a reinforced AEG2.5 Gearbox with adjustable muzzle velocity. Unusual features of this model include full compatibility with electronic systems such as GATE TITAN and the Kinetic Feedback System."
