Latest action on S. 1374: Read twice and referred to the Committee on the Judiciary.

Who this affects: This bill mainly affects people and businesses that own, sell, make, import, or transfer bump stocks, conversion parts, or semiautomatic guns changed to fire faster. Current lawful owners of covered changed guns would need to act within 120 days to register them. Gun dealers and makers would need to stop handling banned devices and follow National Firearms Act rules for covered changed guns. Federal, state, and Tribal agencies would keep authority to use these items for official purposes.

Why this matters: This bill matters because it would turn some fast-fire gun devices and modified guns into clearly banned or tightly controlled items. Today, some of these devices have been treated as a gray area or have faced changing rules. The bill would create a federal ban for conversion devices and a registration path for some already-modified guns. Its real-world effect would depend on enforcement and on how common these devices are.

Key provisions in S. 1374

• The bill defines a semiautomatic gun in federal law. It means a gun that loads the next round by itself, needs a separate trigger action for each shot, and is not a machine gun.
• The ban would start 120 days after the bill becomes law. After that, people could not import, sell, make, transfer, receive, or possess covered devices that make a semiautomatic gun fire much faster or act like a machine gun, when the item affects interstate or foreign commerce.
• The bill covers loose conversion devices and parts kits. It also covers any device, part, or group of parts that removes the need for a separate movement for each trigger function.
• The bill bans possession and transfer of semiautomatic guns changed to fire much faster or act like machine guns. Those guns are allowed only if they meet the bill's grandfather and registration rules.
• Current lawful owners of covered changed guns would have to register them under the National Firearms Act. They would have 120 days after the bill becomes law.
