President Donald Trump announced on Tuesday that he would direct the Department of Justice to begin the rulemaking process for a new regulation that would effectively ban the sale of bump-fire stocks.
“Today, I am directing the Department of Justice to dedicate all available resources to complete the review of the comments received, and, as expeditiously as possible, to propose for notice and comment a rule banning all devices that turn legal weapons into machineguns,” the president said in a memo to Attorney General Jeff Sessions.
Trump had asked the department to review the legality of bump-fire stocks in the wake of the October 2017 mass shooting in Las Vegas where the attacker used a firearm equipped with the device to kill 58 people. In December, the DOJ announced it and the Bureau of Alcohol, Tobacco, Firearms, and Explosives would review the devices.
The stocks modify a semi-automatic rifle in a way that makes it easier to achieve the bump-fire shooting technique that allows the shooter to pull the trigger more frequently than with traditional shooting techniques. Even with the stocks equipped, an individual trigger pull is still required for each individual shot fired unlike fully automatic fire which requires a single trigger pull to fire multiple rounds. That fact has led the ATF to say the bump-fire stocks they have examined in the past do not convert semi-automatic firearms to fully automatic firearms and are not subject to current federal firearms laws.
