U.S. President Donald Trump has signed a memorandum instructing the Attorney General to ban gun modifications like the bump stocks used in the Las Vegas shooting.
Bump stocks allow shooters to fire bullets in rapid succession, essentially turning weapons into a fully automatic firearm.
"We cannot merely take actions that make us feel like we are making a difference, we must actually make a difference," he told reporters at the White House. "We must move past cliches and tired debates and focus on evidence-based solutions."
He says it will be signed into law "very soon".
The announcement follows mounting pressure for meaningful gun control in the wake of the Florida high school shooting in which a 19-year-old gunman claimed 17 lives.
There's no word on whether he'll expand legislation to outlaw the contentious AK-15 assault rifle used in several high-profile mass shootings including Las Vegas, Florida and Sandy Hook.
