Contact Congress about S. 1531: Assault Weapons Ban of 2025

New assault-style semiautomatic guns and magazines over 10 rounds would be banned for most civilian use. Current legal owners could usually keep what they already have, but transfers and storage would face new rules.

Modern Action explains legislation in plain English, helps you choose whether to support, oppose, or ask for changes, and drafts a message tied to the bill, your stance, and the elected officials who can act on it.

Assault Weapons Ban of 2025 is a Senate bill in committee. The latest recorded action: Read twice and referred to the Committee on the Judiciary.

Latest action on S. 1531: Read twice and referred to the Committee on the Judiciary.

Who this affects: This bill mainly affects gun makers, dealers, buyers, and current owners of covered assault-style semiautomatic guns or magazines over 10 rounds. It also affects licensed gun businesses that choose to handle private transfers. Law enforcement, some government agencies, nuclear security teams, and certain licensed companies would keep access under specific exceptions.

Why this matters: The bill would sharply limit future civilian access to certain fast-firing guns and higher-capacity magazines. It would not take away most items that people already legally own. Instead, it would freeze much of the civilian supply, add rules for old items, and create tools for tracking and voluntary buybacks. The bill does not say how much crime or public safety would change.

Key provisions in S. 1531

  • The bill defines “semiautomatic assault weapon” in two ways. It uses listed gun features and long lists of named rifle, pistol, and shotgun models.
  • A “large-capacity ammunition feeding device” means a magazine or similar device that holds more than 10 rounds. It also covers devices that can be changed to hold more than 10 rounds, except for certain .22 caliber tube magazines.
  • The bill bans most importing, selling, making, transferring, or owning of covered assault weapons and large-capacity magazines. The ban applies in interstate or foreign commerce, meaning trade or movement across state or national lines, and includes exceptions.
  • People could usually keep covered guns and magazines they legally had before the law starts. This grandfather rule does not allow new civilian making or importing of those items.
  • Some guns are left out of the ban. These include antiques, most manually operated guns, rimfire-only guns, and specific models listed in Appendix A, plus a narrow shotgun exception.
