SCOTUS To Decide AR-15 Bans

The Supreme Court just agreed to decide whether the Second Amendment protects your right to own an AR-15.

State of play: The Court will hear a pair of cases challenging semi-auto rifle bans in Connecticut and Cook County, Illinois. The question presented is blunt: does the Second Amendment guarantee "the right to possess" AR-15s and "similar semiautomatic rifles"? A dozen states currently ban these guns, usually by outlawing specific models plus any rifle that pairs a detachable magazine with features like folding stocks, pistol grips, or barrel shrouds — cosmetic stuff that has nothing to do with how the gun actually fires.

The legal test: Under District of Columbia v. Heller (2008), the Second Amendment covers "bearable arms" that are "in common use" for lawful purposes like self-defense. Americans own more than 30 million AR-15-style rifles, and surveys consistently show people use them for self-defense, hunting, and target shooting — the textbook definition of "common use." Then came Bruen in 2022, which flipped the burden of proof: states defending a gun law now have to show it's "consistent with this Nation's historical tradition of firearm regulation," using analogs that are actually similar in both purpose and reach.

That's where Connecticut and Cook County are in trouble. Cook County's best historical argument leans on old gunpowder-storage laws — fire-prevention rules aimed at keeping cities from burning down, not banning rifles with adjustable stocks or muzzle brakes. Heller did carve out a tradition of banning "dangerous and unusual weapons," but the plaintiffs point out that phrase requires both dangerous and unusual. The most commonly owned rifle in America doesn't fit that description no matter how a state legislature describes it.

The intrigue: Four justices have already signaled they think these bans are unconstitutional, and two more have shown they're willing to scrutinize the kind of political hand-waving that usually props up "assault weapon" laws. Combine that lineup with the plain text of Heller and the historical burden set by Bruen, and Connecticut and Cook County are staring at a genuinely uphill fight — not a coin flip.

What to watch: A ruling against the bans wouldn't stop at Connecticut and Cook County. It would put every state "assault weapon" law — California, New York, New Jersey, Massachusetts, and the rest — on notice that their statutes rest on the same shaky historical ground. Expect briefing to ramp up through the fall, with oral argument likely early next year and a decision before the term ends in June.

The bottom line: this is the case that finally forces the Court to answer whether the most popular rifle platform in the country is constitutionally protected, or whether states can keep banning guns based on how scary they look.
