Sen. Kirstin Gillibrand joined a Rockville Centre man who survived the Las Vegas concert shooting to call for a federal ban on bump stocks, which the gunman used in the attack, Monday in Washington, D.C.

"I could actually feel the bullets passing right by us and hitting right next to us," says Robert Gaafar, the survivor.

He says so many bullets rained down that night that he thought there had to be more than just one gunman. But police say only Stephen Paddock was responsible for the mass shooting that left 58 dead and more than 500 hurt.

Paddock used a device called a bump stock to fire rapidly. The modifications allow semiautomatic rifles to fire like fully automatic ones.

Gillibrand is introducing a bill to ban the devices nationwide.

"Congress needs to do its job and start protecting people instead of the gun industry's profits," she said.

But Andrew Chernoff, the owner of Coliseum Gun Traders in Uniondale, says passing new laws is not the answer -- even though his store doesn't sell bump stocks.

"We don't need more laws," he says. "We need to enforce the laws we have on the books now."
