<P> With the passage of Senate Bill 880 and Assembly Bill 1135 in June 2016, the state's assault weapon ban has been expanded to include all semi-automatic center - fire rifles and shotguns that have a "bullet button" detachable magazine; effectively repealing a prior law that made "bullet button" magazines required on all newly manufactured weapons with detachable magazines . The sale or transfer of such weapons will be prohibited, effective January 1, 2017 . Those purchased prior to January 1, 2017 must be registered with the DOJ by the start of 2018 .
