National Rifle Association Executive Director Chris Cox said Sunday that the federal government should review “any device” that effectively transforms semi-automatic fire weapons to automatic ones. The gun rights group has previously said that the so-called “bump stock” device that Las Vegas shooter Stephen Paddock used should be regulated.

“It is illegal to convert a semi-automatic to fully automatic,” Cox said on “Fox News Sunday,” calling on the Bureau of Alcohol, Tobacco, Firearms, and Explosives to review the devices. “The ATF needs to do their job, review these and if there is [a need for] further regulation, then we will work on further regulation.”
