A city of Columbus' law banning a gun accessory that allows semi-automatic weapons to be fired rapidly has been overturned by a judge as unconstitutional.
Franklin County Judge David Cain ruled Friday that municipalities can't regulate gun accessories like bump stocks under state law.
Bump stocks drew wide attention last year when a gunman in Las Vegas killed 58 people attending a music festival. Authorities said some of the semi-automatic rifles Stephen Paddock used that night where outfitted with bump stocks that essentially turned them into automatic weapons.
Ohio pro-gun groups Buckeye Firearms Association and Ohioans for Concealed Carry sued Columbus last month after it enacted the ban in May.
Cain upheld a law that allows Columbus to charge some people convicted of violent felonies with misdemeanors for being in possession of a firearm.
