The Supreme Court Will Decide Whether the Second Amendment Protects the AR-15

On June 30, 2026, the Supreme Court agreed to decide whether the Second and Fourteenth Amendments protect the right to possess AR-15-platform and similar semi-automatic rifles. The Court granted certiorari in Viramontes v. Cook County (No. 25-238) and consolidated it with Grant v. Higgins (No. 25-566), setting up a single hour of oral argument expected this fall and a decision likely by mid-2027. These are the first cases squarely presenting the constitutionality of "assault weapon" bans that the Court has agreed to review, after it declined to hear Snope v. Brown in 2025.

A note on terminology: Throughout this article, "assault weapon" and "assault firearm" appear in quotation marks. These are statutory and political labels, not technical firearms terms; the rifles at issue are ordinary semi-automatic firearms defined by legislatures through lists of features. We use the phrases only because that is the language of the challenged laws.

What the Court Agreed to Decide

The question presented is direct: whether the Second and Fourteenth Amendments guarantee the right to possess AR-15-platform and similar semi-automatic rifles. The Court consolidated the two cases for a single hour of oral argument, with future filings proceeding on the Viramontes docket. After more than a decade of avoiding the issue, the Court has agreed to confront the central question head-on: whether the most widely owned rifles in the country are protected arms under the Second Amendment.

The Two Laws Under Review

Viramontes v. Cook County concerns a Cook County, Illinois ordinance — first enacted in 2006 and revised in 2013 — that bans the AR-15 and a long list of similar semi-automatic rifles by feature. That ordinance was a precursor to the statewide ban Illinois adopted in 2023. Cutberto Viramontes and his co-plaintiffs, backed by the Second Amendment Foundation and the Firearms Policy Coalition, challenged it in 2021. The district court granted summary judgment to the county in 2022, and the Seventh Circuit affirmed, concluding the AR-15 falls outside the Second Amendment's protection.

Grant v. Higgins (formerly Grant v. Lamont) arises from Connecticut's "assault weapon" ban, expanded after the 2012 Sandy Hook shooting, which prohibits a set of semi-automatic rifles both by name and by feature. The Second Amendment Foundation and the Connecticut Citizens Defense League brought the challenge; the Second Circuit declined to enjoin the law. In both cases the courts of appeals ruled against the challengers — which is precisely the division the Supreme Court recognized as warranting its attention.

Why Now: The Snope v. Brown Backstory

The timing is not an accident. Just last year, the Court declined to hear Snope v. Brown, a challenge to Maryland's "assault weapon" ban that the en banc Fourth Circuit had upheld. But the denial came with a signal. Justice Kavanaugh wrote separately to say there is a strong argument that AR-15s are in "common use" by law-abiding citizens — noting estimates of roughly 20 to 30 million AR-15-style rifles in circulation — and that it can be analytically difficult to distinguish between military-use and civilian-use characteristics when the rifle is functionally identical in both contexts.

A denial of certiorari has no precedential effect and does not reflect agreement with the lower court's decision. The Court is free to grant review in a later case presenting the same legal question — which is precisely what occurred here. The Kavanaugh statement in Snope signaled where at least one Justice's thinking stood; the cert grant in Viramontes and Grant indicates the full Court was ready to take it up.

The Legal Question: "Common Use" Versus "Dangerous and Unusual"

The case turns on a framework the Court set out in Heller (2008) and sharpened in New York State Rifle & Pistol Association v. Bruen (2022). Under Heller, arms "in common use" by law-abiding citizens for lawful purposes are protected, while weapons that are "dangerous and unusual" may be restricted. Bruen then directed courts to assess gun regulations against the nation's historical tradition of firearm regulation rather than by balancing interests.

The lower courts have splintered on how that framework applies to semi-automatic rifles. Courts upholding the bans have generally concluded that these rifles are akin to military weapons or are especially dangerous, and so fall outside the Amendment's protection. The challengers counter that AR-15s are owned by the tens of millions for self-defense, hunting, and target shooting, which by definition places them in common use, and that a firearm's cosmetic features cannot transform an ordinary semi-automatic rifle into a weapon outside constitutional protection. Viramontes and Grant give the Court the vehicle to resolve that split.

What a Ruling Could Mean

The stakes reach well beyond Illinois and Connecticut. A dozen states and the District of Columbia have enacted "assault weapon" bans — most recently Virginia — and several local governments have their own. A merits decision on whether the Constitution protects these rifles could substantially affect the constitutionality of similar laws nationwide, including Virginia's HB 217/SB 749 and Maryland's ban, both of which use the same feature-based approach.

That said, the outcome, breadth, and reasoning are all unknown. The Court could issue a sweeping ruling on whether these rifles are protected arms, or it could decide the cases on narrower grounds. Predicting the result from a cert grant is a mistake; the only certainty today is that the question will finally be answered.

What the Grant Does Not Do

It is not a ruling. No ban has been struck down. Every "assault firearm" and magazine restriction now on the books remains fully enforceable while the case is pending.

It does not reach magazines. The question presented is about rifles, not magazine capacity. The Court held over the pending large-capacity-magazine cases — including Duncan v. Bonta — rather than granting them, so a decision here may not resolve magazine limits.

It does not address age restrictions. On the same order list, the Court denied the petitions challenging laws that limit firearm purchases by adults under 21.

What It Means for Your Firearms — and Your NFA Trust

For gun owners in ban states, the practical guidance is simple and important: change nothing based on this grant. Do not reconfigure a firearm, acquire a now-prohibited rifle or magazine, or treat any state ban as unenforceable because the Supreme Court agreed to hear the issue. Your compliance obligations are exactly what they were on June 29.

Virginia owners should keep two tracks separate. Enforcement of Virginia's recently enacted ban is currently enjoined pursuant to a preliminary injunction in Crump v. Katz — an order whose scope and durability remain contested and which is covered in our Virginia "assault firearm" ban update — which is an entirely different proceeding from this Supreme Court case. The federal case will unfold over the coming year on its own, slower schedule; it does not lift or extend the Virginia injunction, and the Virginia injunction does not bind the Supreme Court.

For those who hold firearms in an NFA gun trust, the case has particular resonance. An AR-pattern short-barreled rifle built on an approved ATF Form 1 is both a federally regulated NFA item and, in a ban state, potentially a covered "assault firearm" under state law. A decision protecting these rifles could reshape the feature-based state restrictions that most directly affect the rifles owners place in trust — but that possibility is speculative until the Court rules. In the meantime, the trust holds whatever the law permits, and that law has not changed.

Timeline

Merits briefing will run through the summer and fall. Oral argument is expected during the Court's October Term 2026, likely in the fall, although the Court has not yet set an argument date. Consistent with the Court's usual practice, a decision is most likely to arrive by the end of the term in mid-2027. We will update this article as the schedule firms up and as the Court acts.

Frequently Asked Questions

Does this mean AR-15 bans have been struck down?

No. The Court has only agreed to hear the question. No ban has been invalidated, and every existing state and local "assault weapon" ban remains in force unless and until the Court rules otherwise.

Does this affect Virginia's ban?

Eventually and indirectly. Virginia's ban is on a separate track: its enforcement is presently enjoined by a state-court preliminary injunction in Crump v. Katz. A Supreme Court decision on whether these rifles are constitutionally protected could later bear on Virginia's law, but that is a year or more away and the outcome is unknown.

Does the case cover magazines or under-21 restrictions?

No. The question presented is limited to rifles. The Court held over the pending magazine-capacity cases and denied the under-21 age-restriction petitions, so neither is squarely before it here.

Should I change anything I own or plan to build right now?

No. Comply with the law as it currently stands in your jurisdiction. A cert grant is not a decision, and acting as though the bans are already gone can carry serious criminal exposure. If you have questions about what your state's law currently permits, schedule a consultation.
