What AB 1263 does, verified November 24, 2025
This bill aims to amend the law regarding firearms manufacturing, distribution, and possession. It would prohibit the manufacture of certain firearms, including ghost guns, using 3D printing or CNC milling machines. A person knowingly or willfully aiding or abetting the manufacture of these firearms would face a misdemeanor charge. The bill would also establish a new crime for distributing digital firearm manufacturing codes, which include computer-aided design files or other code that can be used to manufacture firearms. A person who owns or participates in the management of an internet website that makes these codes available for purchase or distribution could be presumed to have violated this provision. The bill would require firearm industry members to provide clear and conspicuous notice to prospective purchasers that certain conduct, such as manufacturing firearms without a licens…

LEGISLATIVE COUNSEL'S DIGEST
AB 1263, Gipson. Firearms: ghost guns.
Existing law makes it a crime for a person to manufacture or cause to be manufactured specified firearms. Existing law prohibits a person, other than a state-licensed firearms manufacturer, from using a computer numerical control (CNC) milling machine or three-dimensional printer to manufacture a firearm.
This bill would prohibit a person from knowingly or willfully causing 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 three-dimensional printer or CNC milling machine, as specified. The bill would make a violation of these provisions a misdemeanor.
By creating a new crime, this bill would create a state-mandated local program.
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. For these purposes, existing law defines “digital firearm manufacturing code” to mean any digital instructions in the form of computer-aided design files or other code or instructions that may be used to program a CNC milling machine, a three-dimensional printer, or a similar machine to manufacture or produce a firearm, including a completed frame or receiver or a firearm precursor part. 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 include computer-aided manufacturing files as a digital instruction and include the manufacture or production of a machinegun and specified firearm components, including large-capacity magazines, as part of the definition of digital firearm manufacturing code. The bill would also authorize a person who has suffered harm in California as a result of a violation of these provisions to seek compensatory damages and injunctive relief. The bill would create a rebuttable presumption that a person violated the provision of unlawfully distributing or causing to be distributed any digital firearm manufacturing code if the person owns or participates in the management of an internet website that makes digital firearm manufacturing code available for purchase, download, or other distribution to individuals, and the internet website, under the totality of the circumstances, encourages individuals to upload, disseminate, or use digital firearm manufacturing code to manufacture firearms, as specified.
Existing law establishes a firearm industry standard of conduct, which requires a firearm industry member, as defined, to establish, implement, and enforce reasonable controls, as defined, and to take reasonable precautions to ensure that the member does not sell, distribute, or provide a firearm-related product, as defined, to a downstream distributor or retailer of firearm-related products who fails to establish, implement, and enforce reasonable controls. For these purposes, existing law defines firearm accessory and firearm manufacturing machine.
This bill would require, prior to completing the sale or delivery in California or to a California resident of a firearm barrel that is unattached to a firearm, firearm accessory, or a firearm manufacturing machine, a firearm industry member to comply with specified requirements, including providing a prospective purchaser with clear and conspicuous notice that specified conduct is generally a crime in California, including manufacturing firearms to be sold or transferred to an individual without a license to manufacture firearms.
Existing law, subject to exceptions, provides that any person who has been convicted of certain misdemeanors may not, within 10 years of the conviction, own, purchase, receive, possess, or have under their custody or control any firearm and makes a violation of that prohibition a crime.
This bill would also prohibit any person convicted of specified misdemeanor violations, including manufacturing an undetectable firearm or knowingly or willfully causing another person to engage in the unlawful manufacture of firearms, on or after January 1, 2026, from owning, purchasing, or receiving any firearm within 10 years of the conviction, and makes a violation of that prohibition a public offense punishable by imprisonment in a county jail, a fine, or by both the fine and imprisonment. Because this bill would expand the application of a crime to a larger class of potential offenders, this bill would impose a state-mandated local program.
This bill would make these provisions severable.
This bill would incorporate additional changes to Section 3273.50 of the Civil Code proposed by AB 1127 to be operative only if this bill and AB 1127 are enacted and this bill is enacted last.
The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.
This bill would provide that no reimbursement is required by this act for a specified reason.
The people of the State of California do enact as follows:
