Gov. Dannel Malloy announced today he wants to ban so-called bump stock devices like the ones used last year in the mass shooting at an outdoor Las Vegas concert.

"While bump stocks don't change the mechanics of the weapon they are attached to, they increase the rate of fire to machine gun-like speeds," Malloy says. "Simply put, these devices are cheap. They are deadly. And they are completely and utterly unnecessary in our society."

The device attaches to a semi-automatic rifle and allows it to fire more like a fully automatic weapon. Right now, the modifications are legal in Connecticut. In the Las Vegas shooting, a single gunman used bump stocks to kill 58 people and injure hundreds in just minutes.

"We do not live in a war zone in America," says Po Murray, of the Newtown Action Alliance, a gun-control advocacy group. "There is absolutely no justification for any civilians to own bump stocks or assault weapons and other dangerous accessories."

For the first two years, the first offense for possessing a bump stock would be a $90 fine. After that, possessing or selling a bump stock would be a felony.

If passed, Connecticut would be the third state to explicitly ban bump stocks.

Dean Price, owner of the Wooster Mountain Shooting Range, doesn't allow bump stocks on his range, but he still says he's wary about a ban.

"It's a ridiculous device to put on a firearm, but some people might like it," he says. "It's not up to me to tell them what they should or should not have."

And the Connecticut Citizens Defense League, the state's largest gun rights group, says the ban is a political stunt and claims that a similar effect could be achieved if a shooter used a belt loop, a rubber band or held a rifle a certain way.
