A review by Evike Matt of the EMG SGR-12 Automatic Electric Shotgun made by CYMA. You can say it is a clone of the Tokyo Marui SGR-12 that is an original design by the Japanese airsoft company that uses the same magazine as the Tokyo Marui AA-12 AES including the drum magazine. It is a tri-shot AES and comes with a MOSFET pre-installed.
