U.S. Senator Tim Kaine (D-VA) and 18 Senate colleagues have introduced the Age 21 Act, legislation that would raise the minimum age to buy assault weapons and high-capacity ammunition magazines from 18 to 21.
That's the same age requirement that already applies to buying handguns from federally licensed dealers.
“Everyone in America should be able to live free from the fear of injury or death caused by a firearm,” said Kaine. “One of many commonsense steps we can take to reduce that risk is limiting young people’s access to assault weapons — just like we already limit their access to handguns."
The legislation is endorsed by organizations including Brady: United Against Gun Violence, March for Our Lives, Giffords, Newtown Action Alliance, and Everytown for Gun Safety.
