Since the mass shooting in Las Vegas earlier this month, U.S. representatives from both parties have called for a nationwide ban on bump stocks, Floridians among them.

Stephen Paddock used the accessory to rapidly fire from his legal semiautomatic rifle from a Mandalay Bay Resort hotel room into a crowd gathered for the Route 91 Harvest country music concert, killing 59 people and injuring more than 500.

A bump stock attachment, when used to replace a rifle’s standard stock, allows the weapon to slide back and forth freely and rapidly.

While bump stocks make a semiautomatic weapon fully automatic, the devices are legal. Congress banned fully automatic weapons in 1994 as part of the Public Safety and Recreational Firearms Use Protection Act.

Proposed legislation

There's been a flurry of activity from both parties since the Las Vegas attack:

Sen. Dianne Feinstein, D-California, filed a bill calling for a ban on bump stocks, which Florida's Democratic Sen. Bill Nelson cosponsored.

Sen. Marco Rubio, R-Florida, has not taken a concrete stance on bump stocks yet, telling reporters he was "open" to changes in legislation.

A House companion bill called the Automatic Gunfire Prevention Act was cosponsored by 173 Democrats, including 10 Florida lawmakers.

Rep. Carlos Curbelo, R-Miami, filed a separate ban bill. Cosponsors include fellow Florida lawmakers Ileana Ros-Lehtinen, R-Miami, and Dennis Ross, R-Lakeland.

The National Rifle Association said it opposes all legislation calling for a ban, and its Institute for Legislative Action spokesman called the bills overreaching.

The next day, House Speaker Paul Ryan, R-Wisconsin, said if the devices are outlawed, it should be done through a regulatory change from the Bureau of Alcohol, Tobacco, Firearms and Explosives.

Republican Rep. Bill Posey, who represents Florida's Brevard and Indian River counties, said in a statement he supports a ban. The Las Vegas shooter lived in Posey's district part-time before selling his Viera home in 2015.

Congress hasn't acted on any of the three bills.

In Florida, state Sen. Linda Stewart, D-Orlando, filed a ban bill earlier this week that would make anyone who possesses a bump stock guilty of a third-degree felony, punishable by up to five years in prison or a fine up to $5,000.

State lawmakers in Illinois and City Council members in Tuscon and Cincinnati also have proposed bans.

Bump stock sales

Bump stocks were readily available online before the Las Vegas shooting, but several websites have sold out since then, according to a gun shop owner in Stuart, Florida.

More customers of Aesier Arms have asked for bump stocks over the past few weeks, owner Chris Martin said. But Martin’s never sold bump stocks, and said he never will — not necessarily because of safety concerns, but because they’re “junk.”

“They’re a gimmick for people who can’t really shoot,” he said, adding he doesn't support banning them because they are less of a threat than other weapons.

Martin said he always gets more customers after mass shootings, partially because people want to buy guns they think Congress will ban or regulate after such incidents.

A University of North Florida poll conducted days after the Las Vegas shooting found 52 percent of registered voters in the state oppose banning the sale of assault weapons and large-capacity ammunition magazines.
