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.
