The Supreme Court declined Thursday to take up an appeal challenging a federal ban on bump stocks that went into effect Tuesday.

After the Trump administration outlawed the devices — which allow rifles to be fired rapidly — owners, dealers and manufacturers were required to destroy them by midnight Monday or turn them into a local office of the federal Bureau of Alcohol, Tobacco, Firearms and Explosives. Federal authorities estimated that half a million were sold in the United States.

Bump stocks figured prominently in the 2017 mass shooting at an outdoor concert in Las Vegas that killed 58 people and wounded 500 others. Of 22 semiautomatic rifles in the hotel room used by the gunman, 14 were equipped with bump stocks, prompting President Donald Trump to push for a ban.

Gun rights groups filed two separate Supreme Court appeals. One, directed to Chief Justice John Roberts, was rejected Tuesday. A second, filed with Justice Sonia Sotomayor, was turned down Thursday after she referred it to the full court. In both decisions, the court gave no explanation, following its usual procedure.
