Colorado generally prohibits the knowing possession of a “dangerous weapon,” which includes a machine gun.¹ However, an exception applies for any person with a valid permit to possess a machine gun.²

Federal law requires machine guns to be registered with the Bureau of Alcohol, Tobacco, Firearms & Explosives (ATF), and generally prohibits the transfer or possession of machine guns manufactured after May 19, 1986.³
