Roberti-Roos Assault Weapons Control Act

The Roberti-Roos Assault Weapons Control Act of 1989 is a California law that bans the sale, transfer, and possession of specific semi-automatic firearms classified as assault weapons. It identifies certain features—like detachable magazines, pistol grips, or folding stocks—that define these weapons. The law aims to reduce firearm violence by restricting access to weapons with increased capacity for rapid fire and widespread harm, while allowing for existing possession under specific conditions. It represents one of the early efforts in California to regulate assault weapons more strictly for public safety.
