Michigan prohibits the manufacture, sale, offer for sale, or possession of a machine gun or any other firearm that “shoots or is designed to shoot automatically more than 1 shot without manual reloading, by a single function of the trigger.”1 Note, however, that this prohibition does not apply to a person licensed by the federal government to manufacture, sell, or 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 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
The state also generally prohibits any person from knowingly: 1) manufacturing, selling, distributing, or possessing, or attempting to manufacture, sell, distribute, or possess, a device designed or intended to be used to convert a semiautomatic firearm into a fully automatic firearm; or 2) demonstrating to another person, or attempting to demonstrate to another person, how to manufacture or install a device to convert a semiautomatic firearm into a fully automatic firearm.5 A “fully automatic firearm” is a firearm employing gas pressure or force of recoil to mechanically eject an empty cartridge from the firearm after a shot, and to load the next cartridge from the magazine, without renewed pressure on the trigger for each successive shot.6
