CINCINNATI, OH (FOX19) - It appears the Bump Fire Stock accessory is out of stock in Tri-State area stores.
This was the device used by Stephen Paddock, which helped him kill 58 people in Las Vegas.
The International Business Times reports that Walmart, Bass Pro, and Cabela's have made the item unavailable.
Several gun store owners who declined to be interviewed called the device a gimmick, and did not carry it because there was little demand for it until the Vegas shooting.
One owner who asked not to be named said he received eight phone calls Thursday where people have been asking for it.
Another owner said they go for about $99, and now he sees them online selling for $299. He even said someone came into his Lawrenceburg, Ind. store offering to sell him one -- he said he declined.
The NRA came out Thursday calling on the Bureau of Alcohol and Firearms and Explosives to review whether the device complies with federal law.
Joe Eaton, regional director of the Buckeye Firearms Association, questions whether a ban on the device would work.
"The function of the Bump Fire Stock is to replace something you can already do with any firearm, whether it has an additional stock on it or not," he said.
Eaton went on to say the ATF reviewed the Bump Fire Stock twice during the Obama Administration, and the conclusion was these types of accessories do not alter the firearms in any way that would make them illegal.
On a national television show, Ohio Gov. John Kasich said he would be in favor of outlawing the device, but doesn't think he can get it through the assembly. He said it'd make a lot of sense to get rid of it.
