The "Rhode Island Assault Weapons Ban Act of 2025" introduces significant regulations concerning the possession, manufacture, sale, and purchase of assault weapons in the state. It establishes a new Chapter 47.2 in Title 11 of the General Laws, defining key terms such as "assault weapon," "detachable magazine," and "secure storage." The bill categorizes various firearms as assault weapons, including specific semi-automatic shotguns, rifles, and certain pistols, while excluding firearms that only operate with .22 caliber rimfire ammunition. The legislation prohibits individuals from possessing assault weapons unless they meet specific criteria, with violators facing penalties of up to ten years in prison or fines of up to $10,000, and the potential forfeiture of the weapon.

Additionally, the bill provides a one-year grace period for individuals who lawfully possessed an assault weapon before the bill's effective date to register their weapon, render it permanently inoperable, or surrender it to law enforcement. The registration process requires a $25 fee and includes a fingerprint-supported criminal background check, while ensuring the confidentiality of registrants' information. The act also outlines conditions for lawful possession of registered assault weapons, such as at residences or licensed shooting ranges, and includes provisions for federally licensed firearm dealers. The law is set to take effect on January 1, 2026, and includes a severability clause to maintain the enforceability of remaining provisions if any part is invalidated.
