Analysis: The First Crack Forms in Federal Machinegun Ban
For the first time, a federal judge has ruled the Second Amendment protects civilian machinegun possession.
On Wednesday, US District Judge John W. Broomes dismissed charges against a Kansas man for possessing a fully automatic .300 blackout AR-15 and Glock 33 handgun. He ruled that the federal ban on possessing or transferring machineguns (with limited exceptions) was unconstitutional as applied to the defendant.
“To summarize, in this case, the government has not met its burden under Bruen and Rahimi to demonstrate through historical analogs that regulation of the weapons at issue in this case are consistent with the nation’s history of firearms regulation,” Judge Broomes wrote in US v. Morgan.
In many ways, the decision is the epitome of what some gun-rights advocates hoped the Supreme Court’s 2022 Bruen decision and the new test it laid down would bring to bear on America’s gun laws. The 1934 National Firearms Act (NFA), which marked the first time the federal government regulated machineguns by requiring registration and a $200 tax stamp, has rankled a vocal section of activists. The same is true of the 1986 Firearms Owners Protection Act, a provision of which known as the Hughes Amendment—18 USC § 922(o)—functionally banned civilian ownership of automatic weapons manufactured after its enactment.
Those activists view the federal regulations, enacted for the first time more than 140 years after the ratification of the Second Amendment, as incompatible with the Bruen standard because it prioritizes Founding-era approaches to weapons regulation when evaluating modern regulations. They see the ultimate liberalization of machinegun, suppressor, and short-barreled rifle regulations as the natural apotheosis of courts faithfully applying the Bruen test to America’s modern gun-control regime.
But court after court to address the question in recent years has rejected the idea the Second Amendment protects machineguns, largely based on the Supreme Court’s own words. Most often, they cite a section of the majority opinion in DC v. Heller that discusses the idea that fully automatic M-16s, which are functionally identical to the rifle at issue in Morgan, “may be banned.”
“We also recognize another important limitation on the right to keep and carry arms,” Justice Antonin Scalia wrote for the majority in Heller. “Miller said, as we have explained, that the sorts of weapons protected were those ‘in common use at the time.’ We think that limitation is fairly supported by the historical tradition of prohibiting the carrying of ‘dangerous and unusual weapons.’”
Broomes interrogated this reliance on Heller’s brief discussion of M-16 rifles and reached a different conclusion on how much it binds courts confronting an explicit challenge to the federal ban on new machineguns.
