The Justice Department is finalizing tighter regulations on guns with accessories known as stabilizing braces, a gun-control action touted by President Joe Biden after the devices were used in mass shootings in recent years.
The rule, formalized Friday, was one of several steps Biden announced in April 2021 after a man using one killed 10 people at a grocery store in Boulder, Colorado. A stabilizing brace was also used in a shooting in Dayton, Ohio, that left nine people dead in 2019.
