The manufacturing, importation into the state, offering for sale, keeping for sale, exposing for sale, giving, and lending of a large capacity magazine is controlled. No person may participate in these activities without a permit issued by the Department of Justice. For exceptions, see Penal Code §§12020(b)(19)-(32). Featureless firearm - Making a firearm "featureless" means to not have the "features" that make a firearm "assault weapon" under California law. If the magazine fed firearm does not have qualifying "features" listed under 12276.1 (a), it is not an assault weapon but a California legal firearm. Currently, use of "bullet button" makes firearms with qualifying features as firearms with fixed magazine but starting 1/1/2017, they will become assault weapons and owners have until 12/31/2017 to make firearms featureless or register them as assault weapons. For ARs, removing pistol grip/flash suppressor and keeping the length longer than 30 inches will make the firearm "featureless" and there are stocks on the market that do not meet the definition of "pistol grip". Here are CA DOJ definitions: Flash suppressor - Any device designed, intended, or that functions to perceptibly reduce or redirect muzzle flash from the shooter’s field of vision. Pistol Grip, conspicuously protruding - A grip that allows for a pistol style grasp in which the web of the trigger hand (between the thumb and index finger) can be placed below the top of the exposed portion of the trigger while firing.

If the characteristics that make my firearm a category 3 assault weapon are removed, can I cancel the registration? Can I sell it as regular (non-assault weapon) firearm? Yes. If the defining characteristics establishing a firearm as a category 3 assault weapon are removed, it is no longer an assault weapon and the registration may be canceled. However, once the registration is canceled, you can never replace the characteristic(s) that make it an assault weapon, or you will be in possession of an illegal weapon. To cancel an assault weapon registration, contact DOJ at (916) 227-2153. Once the registration has been canceled, the firearm can be sold or transferred like any other firearm (non-assault weapon)."
