Illinois prohibits the knowing sale, manufacture, purchase, possession or carrying of a machine gun.1 Illinois defines a machine gun as “any weapon, which shoots, is designed to shoot, or can be readily restored to shoot, automatically more than one shot without manually reloading by a single function of the trigger, including the frame or receiver of any such weapon.” Any combination of parts designed or intended for use in converting any weapon into a machine gun, or any combination or parts from which a machine gun can be assembled, also constitutes a machine gun for purposes of these prohibitions.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 In December 2018, ATF finalized a rule to include bump stocks within the definition of a machine gun subject to this federal law, meaning that bump stocks will be generally banned as of March 26, 2019.4
