Bump stocks have been a big topic of conversation among lawmakers after authorities reported the Las Vegas shooter was using them on several of his guns. Some said this type of gun accessory should not be available to everyone because they give a shooter too much power.

Bump stocks can make semi-automatic guns perform like automatics.

Instead of just firing 45-60 rounds per minute, bump stocks allow the guns to fire between 400-800 rounds per minute.

In Texas, anyone can buy a bump stock. There's no background check, waiting period or permit needed. They cost less than $200.

"Now people want to get their hands on one to see what they're all about," Central Texas Gun Works Owner Michael Cargill said.

Cargill hasn't been able to keep them on his shelves.

"They're all sold out all over the country," he said.

On Wednesday, Senator Dianne Feinstein announced her plans to introduce a bill that would place a ban on bump stocks.

"Our bill is simple and straightforward," she said. "Ban manufacturing or possession of accessories that accelerate a semi-automatic rifle to that of an automatic."

Cargill believes this won't be happening anytime soon.

"They can try but you're talking about and accessory," he said. "You're not talking about an actual firearm."

"As a gun owner and a staunch supporter and defender of the Second Amendment, I believe that the recent tragedy in Las Vegas prompts a congressional review of bump stocks and similar devices that allow semiautomatic weapons to behave like automatic weapons, which are currently subject to tight federal licensing requirements," Congressman Bill Flores (TX-17) said.

"I will tell you that the unique aspect of the bump stock and how you would literally transform a semiautomatic weapon into an automatic weapon is something that I think bears looking into," Senator John Cornyn (R-TX) said. "I talked to Chairman Grassley of the Senate Judiciary Committee. I believe that once the investigation is complete and we learn all aspects of what contributed to this event, then we should have a hearing and look into it, and that should include the bump stock but also any other aspect of this terrible crime that we need to look at from a federal perspective."

House Speaker Paul Ryan has indicated the bill is not a priority for GOP leaders.
