Summary

Assembly Member Gipson's legislation targets the unauthorized manufacture and distribution of firearms by establishing new restrictions on digital manufacturing tools and expanding liability for those who facilitate illegal weapon production. The bill prohibits individuals from knowingly aiding or promoting the unlawful manufacture of firearms, including through the use of 3D printers or CNC milling machines, while creating civil and criminal penalties for violations.

The legislation requires firearm industry members to implement specific controls before selling certain components or manufacturing equipment in California. Sellers must provide clear notices about illegal manufacturing activities, verify purchaser age and identity, and follow strict shipping protocols for items like unattached firearm barrels and accessories. The bill also expands the definition of regulated digital firearm manufacturing code to include computer-aided manufacturing files used to produce large-capacity magazines, machine guns, and other restricted components.

Under the measure's enforcement provisions, individuals harmed by violations can seek compensatory damages and injunctive relief, while government attorneys can pursue civil penalties up to $25,000 per violation. The bill creates a rebuttable presumption of illegal distribution against website operators who make digital manufacturing code available in ways that encourage unlawful firearm production. Additionally, those convicted of specified misdemeanors related to illegal weapon manufacturing would be prohibited from possessing firearms for 10 years following conviction.

The legislation adds to existing state oversight of firearm manufacturing by incorporating new definitions, expanding regulated activities, and strengthening both civil and criminal consequences for violations. These changes affect firearm industry members, technology companies producing manufacturing equipment, and individuals involved in weapon production or distribution.
