Legislation making it a crime to sell, purchase, use or manufacture devices to enhance a firearm's rate of fire, including bump stocks cleared the House of Representatives late Tuesday night.
There was bipartisan support Tuesday night for an amendment making such a crime a felony, punishable by up to five years in prison. It passed 114-35.
About a dozen bump stocks were found among weapons used by the man who carried out the October 2017 Las Vegas shooting, which left 58 dead and more than 800 others injured.
Proponents say the bill will keep people safe. But Republican Rep. Rob Sampson says lawmakers would be banning an item that's "never ever been involved in a crime" in Connecticut.
The bill now moves to the State Senate for consideration.
