WASHINGTON, D.C. — U.S. Senator Kirsten Gillibrand, D-New York, has introduced legislation to raise the minimum age to purchase assault weapons and high-capacity ammunition magazines from 18 to 21, the same age requirement that already applies to purchasing handguns from federally licensed dealers.

An individual under the age of 21 used an assault weapon in the 2022 mass shooting at a supermarket in Buffalo that killed 10 people.

“Guns are the leading cause of death for children and teenagers in America today. Year after year, deadly assault weapons inflict devastating and avoidable harm on our families, schools, and communities, causing children, parents, and teachers to live with the fear that the next school shooting may happen in their community,” Gillibrand said. “The Age 21 Act offers a critical safeguard to prevent such tragedies, decreasing the threat of gun violence against our kids. I am proud to support this legislation, and I will fight hard for its passage this Congress.”

The Age 21 Act’s restrictions on the sale of assault weapons, handguns, large-capacity ammunition feeding devices, and related ammunition to individuals under the age of 21 would apply to both federally licensed and private sellers. Additionally, the legislation would bar most individuals under 21 from possessing these items, with limited exceptions for specific circumstances such as service in law enforcement or the armed forces.

The Age 21 Act was originally introduced by Senator Alex Padilla (D-Calif.). In addition to Senator Gillibrand, it is cosponsored by 17 senators: Senators Richard Blumenthal (D-Conn.), Cory Booker (D-N.J.), Chris Coons (D-Del.), Tammy Duckworth (D-Ill.), Dick Durbin (D-Ill.), Mazie Hirono (D-Hawaii), Tim Kaine (D-Va.), Amy Klobuchar (D-Minn.), Chris Murphy (D-Conn.), Patty Murray (D-Wash.), Jack Reed (D-R.I.), Bernie Sanders (I-Vt.), Brian Schatz (D-Hawaii), Adam Schiff (D-Calif.), Elizabeth Warren (D-Mass.), Sheldon Whitehouse (D-R.I.), and Ron Wyden (D-Ore.).
