A bump-stock ban is common sense
A semiautomatic rifle equipped with a “bump stock” can fire at a rate of up to 800 rounds a minute. Does that make it a machine gun? Joe Biden and Donald Trump have said yes. The Supreme Court appears divided.
Typically, when a shooter pulls the trigger of a rifle, it “recoils,” or kicks backward. A bump stock is a device that usually attaches to the back of the firearm and harnesses this rearward force, along with the forward pressure of the shooter, to push the trigger against the shooter’s finger multiple times, enabling them to fire faster than would normally be possible without assistance.

These technicalities are at the center of a case challenging a Trump administration ban on such devices, proposed months after a shooter employed them while killing 60 people and injuring hundreds at a concert in Las Vegas in 2017. Trump’s executive order — which banned the possession and sale of bump stocks, and required gun owners to surrender or destroy them — was enacted over the objections of some Justice Department officials, who said congressional action would be necessary. The Supreme Court is now weighing the evidence. At issue is whether a firearm with a bump stock meets the legal definition of a machine gun —a weapon that fires more than one shot with a single “function of the trigger.” (In 90 minutes of oral arguments, the phrase was uttered no less than 81 times.) The Army veteran and gun-store owner who sued the government claimed that while bump stocks accelerate the rate of fire, they still require “multiple functions of the trigger” because the shooter’s finger pulls it repeatedly.
Defining a deadly weapon shouldn’t be this hard. A firearm that sprays bullets in this manner — whether a trigger is pushed, pulled, pressed or activated by myriad other “functions” — should be considered a machine gun. The federal government has heavily regulated machine guns since the 1930s and has previously banned other devices that convert a firearm into one.
The court will come to its own conclusion. One hopes common sense will prevail. But the responsibility for resolving this issue ultimately resides with Congress: The statutory language applying to machine guns is needlessly ambiguous. Even if the current ban is upheld, administrative actions are inherently less stable than laws. (Two other gun-safety regulations appear headed for the Supreme Court.) That means Congress should get to work.
In the year after the Las Vegas shooting, multiple states — some with Republican governors — passed laws explicitly prohibiting bump stocks. Congress should do the same. It should also restrict possession of other rapid-fire devices, such as trigger cranks and hellfire triggers, as Maryland has done. Such measures have drawn bipartisan support. They also build on notable advances contained in the federal gun-reform package of 2022.
Lawmakers can’t anticipate every technological advance that will make weapons deadlier or harder to trace; just consider downloadable guns, which are made from plastic with a 3-D printer, can evade metal detectors and don’t require a background check. Nor will banning devices stop all illegal activity. But that’s little excuse for inaction. For decades, legislators have failed to clarify overly broad gun laws and left the hard work to agencies, states and courts — all at great peril to the American people.
Whatever the Supreme Court decides, Congress should state the obvious: A gun with a bump stock is a machine gun. It should be illegal.
