A little-known gun accessory that makes semiautomatic weapons fire more like a battlefield machine gun is suddenly getting a lot of attention on Capitol Hill. After authorities found a dozen of these tools -- known as bump fire stocks, or bump stocks -- in the Las Vegas shooter's hotel room, Democrats and Republicans in Congress introduced a bill to ban them. Now, it looks like there's enough support in the House of Representatives from both parties to pass a ban.

The White House and House GOP leadership have said they are open to entertaining the idea. Even the National Rifle Association urged something to be done - though they favor the Trump administration regulating bump stocks rather than Congress outright banning them. So does House Speaker Paul D. Ryan (R-Wis.).

Most lawmakers and the public are just learning what bump stocks are. They essentially move a gun back and forth rapidly against a shooter’s trigger finger so that one pull of the trigger can fire dozens of rounds in seconds.

[All about bump stocks, the deadly gun accessory used in Vegas]

If there's a filibuster, 12 GOP Senators would have to vote for a bump stock ban.

Two have indicated support for the measure.

This rare window of compromise on gun control is nowhere near being a done deal. For one, Congress might toss this to the Bureau of Alcohol Tobacco, Firearms and explosives, which approved the accessory in the first place. If a legislative ban does get far enough in Congress to be considered for a vote by the full Senate, its supporters will likely need 60 votes to clear any filibuster by opponents.

In the House, meanwhile, Democrats would need all 194 of their members plus 24 Republicans to support the ban. It looks like they could be close.
