Retailers are selling out of bump stocks

Bump-fire stocks are typically widely available for purchase on the Internet. WalMart and Cabela’s, two of the nation’s largest gun sellers, appear to have halted online sales of the devices early Wednesday. For retailers that have continued to sell them, business is booming. The webpages of several online retailers state that the devices are sold out.

“Due to extreme high demands, we are currently out of stock. Please check back with us shortly,” reads a notice on the website of Slide Fire Solutions, the manufacturer of a popular bump-fire device.
