JAG Arms shotguns seek to bridge the gap between the airsoft shotgun and traditional real firearm by powering them with green gas propellant. By utilizing green gas, the pump-action feels like the real gun and gives a satisfying pop when fired. The internal green gas storage tank holds 120+ rounds worth of shots at room temperature. One of the most unique features of this shotgun is it's ability to toggle between 3-shot and 6-shot firing modes with the flick of a switch. Loaded with the traditional 28 BB airsoft shotgun shells, the barrel and receiver assembly on this airsoft gun is all metal and rock solid. 3 individual fixed hop up barrels are set for maximum accuracy while still maintaining a shotgun-like spread pattern. A top-mounted picatinny/weaver rail section allows for aftermarket optics mounting such as a red dot reflext sight or low-power 2X magnification scope.
