Illinois House Democrats endorsed a ban on firearm trigger-modifications - including bump stocks like those used in the Las Vegas mass shooting.
The Judiciary committee advanced legislation 7-5 Tuesday. Des Plaines Democratic Rep. Martin Moylan says his legislation would ban "a device used to kill and injure as many people as possible."
Critics say he's overreaching. Todd Vandermyde of the National Rifle Association says it would make criminals of legal gun owners who use after-market devices to make guns shoot faster.
Bump stocks were found on 12 of the rifles stockpiled by the gunman who killed 59 at a Las Vegas concert Oct. 1. They don't affect the trigger but allow more rapid firing.
The national NRA has asked federal officials to examine bump stocks but opposes a ban.
