A bill to prohibit the possession or transfer of certain firearm accessories, and for other purposes.

Automatic Gunfire Prevention Act This bill amends the federal criminal code to make it a crime to import, sell, manufacture, transfer, or possess a trigger crank, a bump-fire device, or any part, combination of parts, component, device, attachment, or accessory that is designed or functions to accelerate the rate of fire of a semiautomatic rifle but not convert the semiautomatic rifle into a machine gun. The bill does not prohibit, with respect to such firearm accessories, the importation or manufacture for, sale or transfer to, or possession by a federal, state, or local government. A violator is subject to criminal penalties—a fine, a prison term of up to 10 years, or both.
