A manufacturer of bump stocks has begun selling the accessories again after temporarily halting their sale in the wake of last month’s shooting in Las Vegas.

Texas-based Slide Fire told customers in an email Tuesday night that bump stocks are again for sale, but in limited quantities, according to Politico.

“We would like to take the time to thank all of our companies for their patience and support throughout the past month," the company wrote in its email. "We have not yet reached adequate inventory levels to offer sales of all products. ... All items are new production and tested at our facility, but may not ship in retail packaging.”

Slide Fire took its bump stocks temporarily off the market after 58 people were killed and more than 500 were injured when Stephen Paddock opened fire at the Route 91 Harvest country music festival last month. The company said on its website at the time it decided to suspend new sales of bump stocks to "provide the best service with those already placed."

Paddock fired down at the crowd from a hotel room on the 32nd floor of the Mandalay Bay Resort and Casino, and police found a dozen bump stocks at the site of the shooting.

Bump stocks effectively turn a semi-automatic weapon into an automatic weapon by using the action of the gun's own recoil to make it fire more rapidly.

A bipartisan group of lawmakers introduced a bill Tuesday that would give the federal government the power to regulate bump stocks. The bill comes after the Bureau of Alcohol, Tobacco, Firearms and Explosives indicated the law would need to be changed in order for it to regulate bump stocks.
