House · HR 2799 · 119th Congress

Closing the Bump Stock Loophole Act of 2025

Summary

This bill bans the import, sale, and possession of devices that make semi-automatic guns fire much faster, like bump stocks. It also bans semi-automatic guns that have been modified to fire like machine guns. People who already own such modified guns have 120 days to register them under federal law.

In Favor

Devices like bump stocks let shooters fire hundreds of rounds per minute, turning legal guns into something close to machine guns. Banning these devices could prevent mass shootings like the 2017 Las Vegas attack. This bill closes a gap that courts said only Congress could fix.

Against

This bill forces owners of legally purchased devices to surrender or destroy them within 120 days, with no compensation for property they bought lawfully. Congress is taking private property without paying for it. Anyone who keeps a banned device becomes a criminal, even if they never used it to harm anyone.

Additional Considerations

Purpose & Problem

Is the problem real and worth federal action?

The bill aims to ban devices that speed up semiautomatic guns to fire like machine guns. It targets bump stocks and similar parts that let a shooter fire many rounds quickly without a separate trigger pull each time.

Scope & Related Provisions

Does it stay focused, or carry unrelated add-ons?

The bill stays on topic by covering the ban on conversion devices, modified firearms, and adding those modified guns to the National Firearms Act registry. All provisions connect directly to the core goal of limiting rapid-fire modifications.

Who Is Affected

Who benefits, and who bears the cost?

Gun owners who have modified semiautomatic firearms must register them within 120 days. Manufacturers, importers, and sellers of these devices face new legal duties. Government agencies and military units are exempt from the ban.

Cost & Funding

Is it affordable and responsibly funded?

The bill does not authorize or appropriate a specific dollar amount. It shifts costs onto a federal agency to manage new firearm registrations and onto private owners and businesses to comply with the ban and registration rules.

Risks & Implementation

What could go wrong in practice?

The bill gives owners 120 days to register already-modified firearms, creating a short window that may be hard to meet. Tracking compliance across many private owners could present a practical challenge for the registry system.
