Senate Bill
No. 704


Introduced by Senator Arreguín

February 21, 2025


An act to amend Section 28235 of, to add Section 16525 to, and to add Chapter 11 (commencing with Section 33700) to Division 10 of Title 4 of Part 6 of, the Penal Code, relating to firearms.


LEGISLATIVE COUNSEL'S DIGEST


SB 704, as amended, Arreguín. Firearms: firearm barrels.
Existing law generally requires the sale or transfer of firearms to be conducted through a licensed firearms dealer. For purposes of these provisions, existing law defines “firearm” to mean a device, designed to be used as a weapon, from which is expelled through a barrel a projectile by the force of an explosion or other form of combustion and to include the frame or receiver of the weapon, including both a completed frame or receiver, or a firearm precursor part. For these purposes, existing law defines “firearm precursor part” as any forging, casting, printing, extrusion, machined body, or similar article that has reached a stage in manufacture where it may readily be completed, assembled, or converted to be used as the frame or receiver of a functional firearm, or that is marketed or sold to the public to become or be used as the frame or receiver of a functional firearm once completed, assembled, or converted.
Commencing on July 1, 2026, this bill would, except as specified, prohibit the sale or transfer of a firearm barrel, as defined, unless the transaction is completed in person by a licensed firearms dealer. The bill would require the licensed firearms dealer to conduct a background check of the purchaser or transferee and to record specified information pertaining to the transaction, including the date of the sale or transfer. The bill would require any costs incurred by the Department of Justice to implement these provisions, which cannot be absorbed by the department, to be funded from the Dealers’ Record of Sale Special Account upon appropriation by the Legislature. The bill would make a violation of these provisions punishable as a misdemeanor. By creating a new crime, this bill would create a state-mandated local program.
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.
Vote: MAJORITY   Appropriation: NO   Fiscal Committee: YES   Local Program: YES  

The people of the State of California do enact as follows:
