The bill amends Section 11-47-2 of the General Laws in Chapter 11-47 entitled "Weapons" to include new definitions and modify existing ones. Notably, it introduces the term "crime gun," which is defined as any firearm used in a crime or suspected by law enforcement of having been used in a criminal offense. Other definitions are updated or added, such as "3D printing process," "binary trigger," "bump-fire stock," and "undetectable firearm," among others. The bill also specifies the meaning of terms like "antique firearm," "ghost gun," "machine gun," and differentiates between types of firearms like rifles and shotguns based on their size and features.

Additionally, the bill adds a new section, 12-1-10.2, to Chapter 12-1 of the General Laws entitled "Identification and Apprehension of Criminals." This section mandates that law enforcement agencies submit any seized "crime gun" or at least two test-fired cartridge cases to the state crime laboratory, the Bureau of Alcohol, Tobacco, Firearms and Explosives (BATF), or any qualified agency for forensic ballistics examinations. The results are to be entered into the National Integrated Ballistic Information Network (NIBIN). Furthermore, information about the firearm, such as make, model, and serial number, must be submitted to the BATF for tracing. The act is set to take effect upon passage.
