Preventing Illegal Weapons Trafficking Act of 2025

This bill aims to stop the spread of “conversion devices” that turn a gun into a machine gun. It tells top federal agencies to create a plan within 120 days to block these parts from being brought into the country or trafficked, and to work closely with state and local police to find, seize, and trace them, including ones made with 3D printers. The bill defines a “machinegun conversion device” as parts made to convert a weapon into a machine gun.

It also updates forfeiture rules so that money and property tied to illegal machine gun trafficking can be taken by the government, and it requires the annual federal gun trafficking report to include how often conversion devices are used in crimes and whether they came from the U.S. or abroad. Agencies must report on their strategy after 120 days and then give updates every two years.

• Who is affected: Federal, state, and local law enforcement; people and groups dealing in machine gun conversion devices.
• What changes: A national plan to detect, seize, and trace these devices; more training and data-sharing; stronger forfeiture rules; added tracking in the federal gun trafficking report .
• When: Strategy and first report due within 120 days of enactment; updates every two years.
