This is the new Spring 3 Shot Combat Tactical Pistol Grip Airsoft true to life shotgun. The UTG M3 shotgun is modeled after the well known Marui M3 Shorty which has been in service for several years. These unique pump action shotguns fire three BBs in one shot so these are actual Airsoft shotguns and not just single shot Airsoft guns that look like shotguns. This multi-shot capability is accomplished by three separate barrels inside of the shotguns main outer barrel.
