High Speed Gunfire Prevention Act This bill provides statutory authority for restrictions on the possession or transfer of bump-stock-type devices and other parts capable of converting a firearm to automatically shoot multiple rounds without manual reloading by a single function of the trigger. It also makes it a crime to import, manufacture, sell, ship, deliver, possess, transfer, or receive parts or accessories designed to accelerate the rate of fire of a semiautomatic firearm without converting it to a fully automatic firearm. An individual who violates this provision is subject to criminal penalties—a fine, a prison term of up to 10 years, or both.
