The National Rifle Association is calling for a review of bump stocks, a weapon modifier that allows semi-automatic weapons to fire faster.
Following the Las Vegas massacre, investigators discovered the device rigged to some of Stephen Paddock's weapons.
"It was kind of a fish and a barrel situation, those bump fire stocks are extremely uncontrollable, but in his case he didn't really need control," Matt Pelham, supervisor at Shooting Sports Inc. in Tampa.
The stocks let a semi-automatic gun perform like a fully-automatic weapon. Pelham tells ABC Action News, his store doesn't sell the modifier and gun buyers are unlikely to find them in any Tampa Bay gun shop.
Bump stocks are typically sold online. But the company that claims to have invented the device, Slide Fire Solutions, has suspended sales.
Polk County sheriff and longtime gun rights advocate Grady Judd wants Congress to ban bump stocks. He also wants a 10-year federal sentence for people who make them, and charge anyone possessing a bump stock with a felony crime.
"Hardcore republicans... talked to me on the phone and told me specifically, 'sheriff you go for it. We need to outlaw those items.'"
Sheriff Judd and the NRA say bump stocks let people to bypass federal law, avoiding the expense and lengthy wait to buy a legal fully-automatic weapon. Buying a fully-automatic weapon can cost between $8,000-$12,000.
According to the U.S. Department of Justice, there are more than 36,000 fully-automatic weapons registered in Florida, the second-highest state in the country.
