Quick answers
Did CA AB 2047 pass?
Yes. CA AB 2047 has been enacted into law. Latest recorded action (2026-09-26): Chaptered by Secretary of State - Chapter 461, Statutes of 2026.
What is CA AB 2047 about?
Existing law makes it a crime to knowingly or willfully cause another person to engage in the unlawful manufacture of firearms or knowingly or willfully aiding, abetting, prompting, or facilitating the unlawful manufacture of firearms, including the manufacture of assault weapons or .50 BMG rifles or the manufacture of any firearm using a 3-dimensional printer, as specified. Existing law authorizes a civil action against a person who knowingly distributes or causes to be distributed any digital firearm manufacturing code to any person, except as specified. Existing law authorizes the Attorney General, county counsel, or city attorney to bring an action against this person and seek a civil penalty, as specified, for each violation, as well as injunctive relief. This bill would require the Department of Justice to check on a quarterly basis beginning no later than July 1, 2027, whether ASTM International has published industry standards for equipping 3-dimensional printers with firearm blocking technology. The bill would require, if the department determines that ASTM International has published or adopted industry standards for firearm blocking technology for 3-dimensional printers, that the department publish written guidance or regulations within 24 months after making that determination. The bill would require, among other things, the written guidance or regulations to describe minimum performance standards for 3-dimensional printer firearm blocking technology before a printer can lawfully be sold or offered for sale in the state. If, as of July 1, 2029, the department determines that ASTM International has not published industry standards for firearm blocking technology for 3-dimensional printers, the bill would relieve the department of any further responsibility to ascertain whether ASTM International has published or adopted industry standards. The bill would make it unlawful to sell, offer for sale, or transfer for consideration, a 3-dimensional printer in the State of California that is not equipped with firearm blocking technology that also meets the above-described industry standards. The bill would exempt printers used exclusively for the manufacturing of properties (props) in the entertainment industry, and would authorize the department to adopt regulations that provide for additional exceptions to these provisions. This bill would also exempt a person who distributes, or causes the distribution of, digital firearm manufacturing code, solely for the bona fide purpose of, among other things, developing, refining, and testing the functionality of a firearm blocking technology from civil liability. This bill would make these provisions severable.
