The National Rifle Association, an influential US gun-lobby group, has called for additional regulation to be implemented concerning “rapid fire” attachments on weapons, akin to those used by the Las Vegas gunman.
“Bump stocks” are a rapid-fire device which allows semiautomatic rifles to fire faster.
Twelve of the rifles the gunman in the Las Vegas mass shooting were modified with the tool.
“Devices designed to allow semi-automatic rifles to function like fully-automatic rifles should be subject to additional regulations,” the group said.
Senior Republicans in Congress – who have long resisted any gun controls – have indicated they are open to banning the device.
