The bill, known as the "Rhode Island Assault Weapons Ban of 2024," amends Title 11 of the Rhode Island General Laws by adding a new chapter, Chapter 47.2, which defines and prohibits assault weapons. Assault weapons are characterized by their semi-automatic function and specific features, such as capacity exceeding six or ten rounds for shotguns and rifles respectively, and the presence of a pistol grip or telescoping stock. The bill exempts semi-automatic rifles with attached tubular devices for .22 caliber rimfire ammunition. It prohibits the manufacture, sale, transfer, purchase, possession, or control of assault weapons, with penalties including imprisonment, fines, and forfeiture of the weapon. Exceptions are made for individuals who lawfully possessed an assault weapon before the effective date of the chapter, allowing them to register the weapon, render it inoperable, surrender it, or transfer it under certain conditions.

The bill also sets forth a registration system for assault weapons owned before the act's effective date, requiring a registration statement, background check, and a $25 fee per weapon. Confidentiality is maintained for the names and addresses of those issued a certificate of possession. Conditions for lawful possession, transport, and transfer of assault weapons are detailed, with violations leading to fines, imprisonment, and forfeiture. The bill includes a severability clause to maintain the validity of the remaining provisions if any part is found invalid, and it takes effect upon passage.
