The CYMA M3 is a 3-round burst multi-shot shell loading airsoft shotgun that is available at many reputable airsoft retailers. Based on the Tokyo Marui M3 airsoft shotgun, this has a full metal receiver, full stock design with pistol grip, and Polymer stock and pistol grip. Max Cherepenin takes a good look at this in this video review... "Hope you guys enjoy this airsoft review! Pretty great shotgun given its price point, highly recommend it to beginners."
