Your AR-15 Heads to the Supreme Court

The most popular rifle in America is about to get its day before the nation's highest court. The Supreme Court has set Dec. 2 for argument in Viramontes v. Cook County, consolidated with Grant v. Higgins, a challenge to Connecticut's ban. Both cases ask whether governments can prohibit AR-15-style semiautomatic rifles consistent with the Second Amendment.

The cases

The justices agreed to take the cases on June 30, 2026. Viramontes comes from the Seventh Circuit and challenges a Cook County, Illinois, ordinance. Grant comes from the Second Circuit and challenges Connecticut's ban, which the state expanded after the 2012 Sandy Hook school shooting. According to SCOTUSblog's reporting, the lower courts upheld the bans in both cases before the justices stepped in.

As reported, the question the Court framed in Viramontes is whether the Second and Fourteenth Amendments protect the right to possess AR-15-platform and similar semiautomatic rifles that are in common use for lawful purposes. That phrase, "common use for lawful purposes," matters. It comes straight from the Supreme Court's own Second Amendment precedent, and it is the foundation of the challengers' argument.

The Justice Department filed a 40-page amicus brief supporting the challengers, according to coverage. A decision is expected by the end of the Court's term, which typically means late June 2027.

What the Court has already said

In District of Columbia v. Heller in 2008, the Court held that the Second Amendment protects an individual right to keep and bear arms, and that the handgun ban in the District was unconstitutional. In New York State Rifle & Pistol Association v. Bruen in 2022, the Court said gun regulations must be consistent with the nation's historical tradition of firearm regulation. Those are the rulings the lower courts are expected to apply. Challengers will argue that a rifle owned by millions of Americans for hunting, sport and home defense is the textbook example of an arm in common use. The states and the county will argue that these rifles are especially dangerous and that history allows legislatures to restrict them. We have not reviewed their briefs, and the strongest version of their argument deserves a fair hearing.

The take

This is the case conservatives and gun owners have waited for. For years lower courts have let jurisdictions ban the most widely owned rifle in the country, in some places on reasoning that treated a constitutional right as a second-class entitlement. If the Second Amendment means anything, it cannot mean that a legislature may prohibit the commonly owned arms of ordinary citizens because the weapon looks frightening. Rights do not depend on how a gun looks.

Honesty also requires saying what this case is not. It is not a ruling yet, and nobody should assume the outcome. The Court agreed to hear the cases, which is not the same as agreeing with the challengers. Oral argument often reveals more than the cert grant, and the justices could write narrowly. Predictions of a sweeping victory are forecasts, and gun-rights supporters who have been disappointed before know better than to count a verdict before it arrives.

Nor should the other side's concern be waved away. Supporters of these bans point to mass shootings, including Sandy Hook, and they are right that the country has paid a terrible price for them. The constitutional question is whether the answer to that grief may be to strip a right from millions of law-abiding owners. A free country has to be willing to ask that question in open court, which is what will happen on Dec. 2.

Whatever the outcome, the stakes extend well beyond Illinois and Connecticut. A ruling in either direction will shape the laws of every state that has restricted these rifles or is considering it. For anyone who owns one, who is thinking of buying one, or who simply cares what the Constitution says, December 2 belongs on the calendar. Expect the decision by the end of June 2027, and expect both sides to claim they were on the winning side of history until the Court says otherwise.
