L'antre Du Dingo got the new AceTech Quark-K tracer unit designed for the Tokyo Marui KSG Gas Shotgun. It is not only a trace unit as it has an integrated torch. With the BiFrost tech, it can do multicolour effect and the ability use regular BBs instead of just Tracer BBs. With its gyro sensor, it will automatically switch on/off the torch depending on the position of the tracer unit.
