The National Rifle Association (NRA) has called for "additional regulations" on bump-stocks, a rapid fire device used by the Las Vegas massacre gunman.
The group said: "Devices designed to allow semi-automatic rifles to function like fully-automatic rifles should be subject to additional regulations."
Republicans have said they would consider banning the tool, despite years of resisting any gun control.
Lawmakers plan to hold hearings and consider a bill to outlaw the device.
The NRA called on Thursday for regulators to "immediately review whether these devices comply with federal law".
President Donald Trump later told reporters his administration would be looking into whether to ban them "in the next short period of time".
"In the aftermath of the evil and senseless attack in Las Vegas, the American people are looking for answers as to how future tragedies can be prevented," NRA chiefs Wayne LaPierre and Chris Cox wrote in the statement.
They criticised politicians who are calling for gun control, writing that "banning guns from law-abiding Americans based on the criminal act of a madman will do nothing to prevent future attacks".
The statement, the organisation's first since Sunday's attack in Las Vegas that left 58 people dead and nearly 500 injured, noted that bump-stocks were approved by the Obama administration's Bureau of Alcohol Tobacco and Firearms.
