WASHINGTON - Several Republican members of Congress support a ban on the kind of device the Las Vegas gunman used to greatly increase the rate of firing, a sign of possible movement on gun restrictions.

It’s a given that Democrats support legislation to ban “bump-stocks,” and many will argue that it’s only a small step. But the GOP as a whole has long resisted any new gun regulations until now.

So far, Republican Reps. Carlos Curbelo, Ileana Ros-Lehtinen, Gus Bilirakis, Vern Buchanan and Tom Rooney have said they would support a ban. Rep. Mario Diaz-Balart said: “I believe it’s time Congress seriously consider the legality of bump stocks.”

UPDATE: Reps. John Rutherford and Dennis Ross also joined the call.

Rutherford: “I believe it is time for Congress and federal regulators to evaluate the regulation of bump-stocks. I signed on to a letter sent to the Bureau of Alcohol, Tobacco, Firearms and Explosives urging them to re-evaluate the regulation of bump-stock devices. On the morning of October 2nd, we were shocked to awaken to news of the horrific event in Las Vegas and the role bump-stocks may have played. It is our duty as legislators to review policies to keep our citizens safe while ensuring the protection of our constitutional rights.”

Ross: “Responsible gun owners understand the importance of reasonable regulations to ensure public safety. That’s why I believe in taking the important step to outlaw devices that make a firearm simulate an automatic firearm. I fully support the Second Amendment and the right to keep and bear arms—this is about consistent enforcement of the automatic weapons ban.”

Rep. Bill Posey favors a ban too.
