This bill, named the "Assault Weapons Ban of 2025," aims to regulate certain firearms and ammunition feeding devices. Its primary purpose is to prohibit the future importation, sale, manufacture, transfer, and possession of specific semiautomatic assault weapons and large capacity ammunition feeding devices. The legislation also includes provisions for existing items, background checks, and buy-back programs. The bill extensively defines a semiautomatic assault weapon based on a combination of features, such as pistol grips, threaded barrels, and folding stocks, when present on semiautomatic rifles, pistols, and shotguns. It also explicitly lists numerous specific models of AK-type, AR-type, and other rifles, pistols, and shotguns that fall under this classification. A large capacity ammunition feeding device is defined as any magazine or similar device capable of holding more than 10 rounds of ammunition, with an exception for .22 caliber rimfire tubular devices. Under the proposed law, it would be unlawful to import, sell, manufacture, transfer, or possess these defined semiautomatic assault weapons and large capacity ammunition feeding devices in interstate or foreign commerce. However, the bill includes a grandfathering clause , allowing individuals to retain possession of any such weapons or devices that were lawfully owned prior to the bill's enactment date. This means existing owners would not be required to surrender their currently owned items. Several exemptions are provided for the general prohibition. These include firearms that are manually operated (bolt, pump, lever, or slide action), permanently inoperable weapons, antique firearms, and those capable only of firing rimfire ammunition. Additionally, the ban does not apply to government entities, qualified law enforcement officers (including campus law enforcement), or licensees under the Atomic Energy Act for security purposes. Licensed manufacturers and importers may also possess these items for testing or experimentation, and a specific list of exempted firearms is provided in Appendix A. For grandfathered semiautomatic assault weapons, the bill introduces new requirements. Owners must ensure these weapons are securely stored or equipped with a safety device if they could be accessible to individuals prohibited from possessing firearms. Furthermore, private transfers of grandfathered semiautomatic assault weapons between unlicensed individuals will require a background check conducted through a licensed firearms dealer. The Attorney General is tasked with maintaining a public record of banned weapons used in crimes and may issue regulations for these background checks, including setting maximum fees. To facilitate the removal of these weapons from circulation, the bill amends federal law to allow Byrne grants to be used for funding buy-back programs for semiautomatic assault weapons and large capacity ammunition feeding devices. This provision aims to offer a voluntary mechanism for owners to surrender prohibited items. Finally, a standard severability clause ensures that if any part of the Act is deemed unconstitutional, the remaining provisions will still stand, preserving the core intent of the legislation.
