Republicans are weighing whether to pass a ban on bump-fire stocks

The devices help semi-automatic firearms fire at an increased rate

CNN  — 

Florida Republican Rep. Carlos Curbelo is planning to introduce legislation Thursday to ban the sale of bump fire stocks, an accessory that can allow semi-automatic firearms to rapidly increase their rate of firing rounds, similar to that of an automatic weapon, which are restricted by federal law.

“I think we are on the verge of a breakthrough when it comes to sensible gun policy,” Curbelo told reporters Thursday, saying his office has been “flooded” with calls from other lawmakers asking about the bill.

He said that the shooting in Las Vegas, where the shooter appeared to modify several weapons with bump stocks to fire rounds more quickly, demonstrated that these devices, are in his opinion at the “outer limits of what the law allows, in this case something that we strongly believe should be illegal.”

“This is such a blatant exploitation of the law, circumvention of the law, that the growing bipartisan consensus is a product of,” Curbelo said about the shift after years of inaction by majority of congressional Republicans on gun legislation.

Curbelo’s comments follow those of House Speaker Paul Ryan, a Wisconsin Republican who signaled openness Thursday to looking into bump fire stocks, and other Republicans have shown an openness to at least discussing a ban on the devices.

In the wake of the Vegas shooting, Ryan told Hugh Hewitt in an interview for his MSNBC show that “clearly that’s something we need to look into.”

Ryan’s comments come as one senior House GOP member told CNN enough House Republicans are likely to agree to a push for legislation that would ban bump stocks that something could pass in the GOP-controlled House.

“There’s enough Republicans who are looking for something that they can say ‘I did something.’ And the bump stock is an Obama policy. That was approved by the ATF in 2010 and 2012, so why would we defend that?”

The ATF said in 2010 that it did not believe bump stocks to be regulated under existing gun laws because it is a firearm part.

This source believed that there would be a GOP-sponsored bill from a group of moderate Republicans that would narrowly address the issue. While many in the GOP conference will oppose it, this member believed based on conversations with colleagues that there would not be a huge pushback to block it, even from the National Rifle Association.

In fact, the NRA announced Thursday that it supports a review of bump fire stocks to see if they are in accordance with federal law.

“The National Rifle Association is calling on the Bureau of Alcohol, Tobacco, Firearms and Explosives (BATFE) to immediately review whether these devices comply with federal law,” the NRA said in a statement. “The NRA believes that devices designed to allow semi-automatic rifles to function like fully-automatic rifles should be subject to additional regulations.”

It’s unclear how the legislation would be drafted, but the easiest way would be to simply reverse current ATF policy rather than institute a ban on the manufacture and sales of the accessories.

In his comments, Ryan said that he – like a lot of members of Co
