On its website Tuesday, Slide Fire Solutions said it "will cease taking orders for its products and shut down its website."
The company said it will process and ship all orders taken prior to May 20. The company did not say on its website what will happen to its factory in Texas.
Slide Fire did not return messages from CNNMoney.
Bump stocks are attached to semiautomatic rifles to speed up their rate of fire to mimic full auto. They were approved by the Bureau of Alcohol, Tobacco, Firearms and Explosives in 2010.
Slide Fire came under criticism after a dozen rifles fitted with bump stocks were found in the Las Vegas hotel suite of Stephen Paddock, who used a perch in his room to kill 58 people and wound hundreds of others on Oct. 1, 2017.
The accessories were selling briskly after the mass shooting in Las Vegas. Slide Fire would occasionally run out of inventory and suspend sales, and then eventually start selling them again. This is the first time the company, based in Moran, Texas, has said it was shutting down its website.
