A machine revolver is a firearm based on the actions of an automatic revolver but with the capabilities of rapid full-automatic fire. This concept is also intended as an alternative to the water jackets found on early machine guns, which would lack the effort of changing barrels on GPMGs during a heavy firefight in a battlefield environment. It must be noted that a machine revolver is NOT in any way related to the Gatling gun and its derivatives as it is basically a machine gun that changes its barrels/chambers for each shot.
