The bill proposes amendments to sections 11-47-2, 11-47-8, and 11-47-42 of the General Laws in Chapter 11-47, which is focused on "Weapons." It introduces new definitions for terms such as "3D printing process," "binary trigger," "bump-fire stock," "ghost gun," and "stun gun," and clarifies what constitutes a "major component" of a firearm. The definition of "ghost gun" is particularly important as it refers to a firearm without a serial number as required by federal law. The bill also defines an "undetectable firearm" as one that cannot be detected by standard security screening devices or is made entirely of certain materials without a serial number.

The bill includes new legal language that requires a license or permit to carry a pistol, revolver, or stun gun, and sets conditions for carrying these weapons with permits from other states. It prohibits the possession of certain automatic weapons and devices that enable semi-automatic weapons to fire automatically, as well as the manufacture, sale, or possession of ghost guns, undetectable firearms, or firearms produced by 3D printing, with some exceptions. The bill revises the list of prohibited weapons to exclude stun guns, allows individuals 18 and older to purchase or possess stun guns with certain restrictions, and criminalizes the sale of stun guns to minors, their use in crimes, and against police officers. The act would be effective upon passage.
