A U.S. appeals court blocks a ban on rapid-fire 'bump stocks'• NPR
The ban was instituted after a gunman perched in a high-rise hotel using bump stock-equipped weapons massacred dozens of people in Las Vegas in 2017. Gun rights advocates have challenged it in multiple courts. The 13-3 ruling at the 5th U.S. Circuit Court of appeals is the latest on the issue, which is likely to be decided at the Supreme Court.
The decision doesn't have an immediate effect on the ban though because the case now moves back to the lower court to decide how to proceed.
