Preventing Illegal Weapons Trafficking Act of 2025

This bill requires federal agencies to develop a strategy within 120 days to prevent the trafficking of machinegun conversion devices - parts that convert regular firearms into machineguns. The strategy must improve detection, coordination between federal and local law enforcement, tracing of devices used in crimes, and address emerging threats like 3D-printed devices. It mandates annual reports to Congress on implementation progress and requires the Attorney General to include specific data on these devices in annual firearms trafficking reports. The bill directly affects federal agencies (ATF, FBI, Homeland Security), state/local law enforcement, and aims to disrupt trafficking networks.
