In Committee

GOSAFE Act

119th Congress Introduced Apr 9, 2025

Analysis under review: This bill has generated analysis that may be too generic or incomplete. Clause-level evidence remains available below.

Summary

This bill would ban the sale, manufacture, transfer, and importation of gas-operated semi-automatic firearms and large capacity ammunition feeding devices that hold more than 10 rounds. It defines gas-operated broadly to include long stroke piston, short stroke piston, direct impingement, blowback, and recoil-operated systems. Existing owners can keep their firearms but cannot transfer them except to licensed dealers or family members. The ATF would maintain a list of prohibited firearms and review applications from manufacturers seeking approval for new semi-automatic designs. Violations carry fines up to ,000 and up to 12 months imprisonment, with enhanced penalties of 2-10 years for committing another federal crime while possessing a banned firearm. The bill also allows Byrne Justice Assistance Grant funds to be used for gun buy-back programs.
