The bill establishes a new crime concerning the possession of digital instructions for the illegal manufacture of firearms and firearm components, introducing the definition of "firearm digital instructions." This term refers to digital files or code that can be utilized to program a three-dimensional printer to create firearms or their components. The legislation aims to address the increasing accessibility of 3D printing technology in firearm production, thereby enhancing public safety and regulating the manufacturing process of firearms.

Additionally, the bill amends existing laws related to prohibited weapons and devices, reinforcing penalties for the possession of certain firearms and components. Specifically, it stipulates that individuals who are not licensed or registered to manufacture firearms and knowingly possess such digital instructions will be guilty of a third-degree crime, which can lead to a prison sentence of three to five years, a fine of up to $15,000, or both. This legislative change is part of a broader initiative to strengthen firearm regulations in New Jersey in response to evolving technologies and to ensure public safety by preventing unauthorized manufacturing. The act is set to take effect immediately upon passage.
