The AR-15 rifle is legal in California, but it must comply with the state's strict gun laws. Features such as detachable magazines, pistol grips, and flash suppressors are restricted. To own an AR-15, it must be registered, and owners must adhere to specific regulations, including background checks and waiting periods. https://www.cordeliagunexchange.com/what-is-a-california-compliant-ar-15-rifle/
