The National Rifle Association says the "bump stocks" device that the Las Vegas shooter used to turn semi-automatic rifles into fully automated weapons should be "subject to additional regulations."
In a statement on Thursday, the NRA says the Bureau of Alcohol, Tobacco, Firearms and Explosives should immediately review whether these devices comply with federal law.
The organization which holds a powerful sway over members of Congress dismissed some of the initial response from lawmakers who have pressed for more gun control.
Said the NRA: "Banning guns from law-abiding Americans based on the criminal act of a madman will do nothing to prevent future attacks."
The statement came from NRA leaders Wayne LaPierre and Chris Cox.
