Devices that convert semiautomatic firearms to fire at rates approaching a machine gun — including bump stocks and similar modifications — would be banned under federal law. Anyone who already owns a modified semiautomatic firearm would have 120 days to register it under the National Firearms Act, which involves the same process used for machine guns. Selling, manufacturing, importing, or possessing an unregistered conversion device or modified firearm would become a federal crime. Law enforcement and military are exempt, and previously modified firearms that are properly registered can still be legally possessed and transferred.
