The NRA’s statement comes after the massacre of 58 people in Las Vegas, by a gunman who used a modified weapon to fire down at a crowd, scrambled the politics of gun control. In interviews since Monday morning, multiple Republicans in congressional leadership — including House Speaker Paul D. Ryan (R-Wis.) — have called for a hard look at bump stocks. Rep. Carlos Curbelo (R-Fla.), a moderate Republican facing a tough 2018 reelection campaign, is expected to introduce a bipartisan bill to ban the devices.

The NRA’s framing of the issue echoes an argument made Thursday morning by White House adviser Kellyanne Conway that the deregulation of bump stocks had been an Obama administration blunder.

“It was President Obama’s ATF, the Bureau of Alcohol, Tobacco and Firearms, in 2010 that decided not to regulate this device,” she told CNN’s Chris Cuomo. “That should be part of the conversation and part of the facts that you put before your viewers.”

The Obama administration’s role in the deregulation was previously reported by The Washington Post; on Wednesday, Obama-era ATF official Rick Vasquez, who approved the devices, said that they were intended “for those guys who want to look like super ninja when they’re out on the range.” At the time, the Obama administration did not think they contravened federal regulations against machine guns, as they did not modify the machinery of guns themselves.

But in the wake of the Las Vegas massacre, Washington seemed increasingly ready to dump bump stocks. In another part of its statement, the NRA emphasized that it was still working toward the pro-gun priorities it had been trying to advance this year.
