“So this is an AR-15, something that's sold all over the United States, completely legal, semi-automatic weapon. This is what the news media sometimes doesn't understand is not a common weapon. It is not available anywhere in the United States unless you have a whole lot of money or a lot of documentation to buy it. This is a full-auto gun. Although they look similar, that's where the similarities end,” Ken Thomas, owner of Texas Gun Shop, explains.

“We've heard a lot lately, especially with the Vegas shooting, the bump stock. Can you explain what that does?” Senora Scott asked.

“That's a device that goes onto the back of a semi-auto weapon. It loops in around this system here, and it's 100 percent approved by the ATF, but what it basically does is, as the gun recoils, it allows the finger to keep pulling the trigger,” Thomas said.

“If someone asks why even add that or make that modification, what would you tell them?” Scott asked.

“Some people just like to have the simulation of something like a full-auto. For me I always look at it as do we have cars that exceed the speed limit?” Thomas said.

“An enthusiast, a hobbyist?” Scott asked.

“Sure, sure. It would be an enthusiast, a hobbyist that wanted to simulate a full-auto weapon. It is by no means the same as a full-auto weapon whatsoever,” Thomas said.

“People are saying that, that bump stock turns this into this but that's not the case,” Scott said.

“No, it kind of simulates it somewhat but the rate of fire on this gun would be extremely high compared to the bump stock. There's no way it would have the capabilities of this firearm. And that's one of the reasons these guns are highly restricted. They aren't on the streets. No one can easily modify this gun (semi-automatic) to be the same as this gun (fully automatic),” Thomas said.

Thomas said that he doesn't keep bump stocks in his store. He said that bump stocks aren't even very popular. When it comes to fully automatic rifles, the common person cannot go into a gun store to buy them. They are extremely regulated by the government.
