assault weapons; magazines; prohibition; registration

HB 2421 prohibits private possession of assault weapons (defined as firearms with features like detachable magazines or specific stocks) and large-capacity magazines in Arizona. It applies to most residents, with exceptions for law enforcement, military personnel, and licensed dealers selling to those agencies. The bill requires existing owners to either surrender, permanently disable, or register their weapons within 90 days, including annual background checks and strict storage rules. Violations carry fines starting at $750 for first-time possession offenses, escalating to $5,000 for felony violations. The law does not affect government or military use, and registration is mandatory for retained weapons.
