The Roberti–Roos Assault Weapons Control Act of 1989 (AWCA) is a California law that bans the ownership and transfer of over 50 specific brands and models of firearms, which were classified as assault weapons. Most were rifles, but some were pistols and shotguns. The law was amended in 1999 to classify assault weapons by features of the firearm. Firearms that were legally owned at the time the law was passed were grandfathered if they were registered with the California Department of Justice. The law was overturned in June 2021 in Miller v. Bonta; the ruling is stayed pending appeal.
