General-purpose machine gun

A general-purpose machine gun (GPMG) is an air-cooled, fully automatic weapon that can be adapted to light machine gun and medium machine gun roles. A GPMG weapon will typically feature a quick-change barrel, configuration for mounting on bipods, tripods, and vehicles as infantry support weapons, and calibered to fire full-powered rifle cartridges such as the 7.62×51mm NATO, 7.62×54mmR, 7.5×54mm French, 7.5×55mm Swiss, and 7.92×57mm Mauser.
