The proposed bill seeks to enhance firearm regulations in New Jersey by prohibiting the possession and sale of machine gun conversion devices, which are defined as any apparatus designed to modify a semiautomatic firearm to enable it to fire multiple shots with a single trigger pull. The bill introduces new legal language that categorizes the possession of such devices as a third-degree crime, regardless of whether the individual possesses a firearm. Additionally, it modifies the existing definition of "machine gun" to include firearms equipped with a machine gun conversion device or a trigger crank, thereby broadening the scope of what constitutes a machine gun under state law.

Furthermore, the legislation criminalizes the manufacturing, transporting, selling, or disposing of machine gun conversion devices, also classifying these offenses as third-degree crimes. The penalties for these offenses include three to five years of imprisonment and fines up to $15,000. The bill reflects a legislative effort to address gun violence and improve public safety by tightening restrictions on dangerous firearm modifications, aligning with recommendations from the New Jersey State Commission of Investigation regarding illegal firearms use. The act is set to take effect six months after its enactment.
