Sen. Dianne Feinstein on Tuesday rejected a plan by the Alcohol, Tobacco, Firearms and Explosives Bureau to review the sale of bump stocks and other devices that can accelerate the firing power of semi-automatic weapons, arguing the ATF is not authorized to regulate them and instead Congress must act.
"The ATF lacks authority under the law to ban bump-fire stocks, period," the California Democrat said in a statement. "The agency made this crystal clear in 2010 and again in a 2013 letter to Congress, writing that ‘stocks of this type are not subject to the provisions of federal firearms statutes.'"
Feinstein said, if the ATF decides to regulate the devices, gun manufacturers would sue.
"Gun manufacturers make millions selling these devices and they would seize on an agency flip-flop to tie up new regulations for years," Feinstein said.
Feinstein wants Congress to take up legislation banning devices that accelerate firing power, but Republicans favor ATF regulation.
A bump stock is the type of device used in October by the Las Vegas shooter, who opened fire on a country music festival using multiple guns, killing 58 people and injuring more than 500.
