The National Rifle Association - the influential pro-gun lobby group - said bump stocks should be "subject to additional regulations" and called on regulators to determine whether the devices comply with federal law.
"Oh, God, yes, it's been insane".
The organisation, which holds a powerful sway over members of Congress, dismissed some of the initial response from lawmakers who pressed for more gun control after Stephen Paddock shot dead 58 people attending a music festival. However, the Las Vegas massacre has re-ignited a long-standing and seemingly unresolvable debate in the United States about the country's gun control laws and regulations - or lack of the same.
Dianne Feinstein, the Senate Judiciary Committee's top-ranking Democrat, responds to revelations that some of the weapons Las Vegas shooter Stephen Paddock used to commit the worst mass shooting in USA modern history Sunday were apparently outfitted - legally - with bump stock devices.
But the sounds of gunfire from videos of the attacks offer a clue. "The NRA believes that devices created to allow semi-automatic rifles to function like fully-automatic rifles should be subject to additional regulations". "We certainly welcome that, would like to be part of that conversation", Sanders said on Thursday.
"They do sell a little bit, but it's very minimal", he said.
Rep. Chris Collins, R-N.Y., said action on guns after Las Vegas was unnecessary. "I am unable to reorder because of the demand".
Calesa said the store began receiving calls from customers about bump stocks on Tuesday.
Trump attempts to say 'Puerto Rico' with a Spanish accent, fails spectacularly
Before the trip, Ms Cruz had begged the federal government for more aid, warning them that people on the island were dying. And he used an exaggerated Spanish accent several times while saying the territory's name.
Sen. David Perdue, R-Ga., originally thought bump stocks were illegal. These comments and the President's blind support for the NRA's unsafe agenda are soul-crushing - not just because I'm a gun violence survivor, but also because I vote in this country and I care about how I leave it for my daughter.
Some retailers, including Walmart and Cabela's, that sold bump stocks online have taken the items off their sites. The gun industry group, the National Shooting Sports Foundation, declined to comment.
The Las Vegas shooter seems to have been the most law-abiding killer in American history, right down to his bump stocks - the attachment that makes a single-shot assault weapon fire more like a machine gun. The accessories are legal. "I think that's our right as Americans, but I don't understand the use of this bump stock and that's another reason to have a hearing", Senator John Cornyn, the No 2 Republican in the Senate, told reporters.
Senior congressional Republicans say they are open to considering legislation banning "bump stocks" like the shooter in Las Vegas apparently used to make semi-automatic rifles perform more like fully automatic weapons.
In an interview with MSNBC, he added: "I didn't even know what they were until this week". "It's not safe, they don't work, and it's a gimmick".
But there are also less expensive legal products that can allow semi-automatic rifles such as the AR-15, which are much more widely available, to fire hundreds of rounds per minute. "If you really want to get a full automatic, pony and get a real one".
