The Supreme Court Confronts AR-15 Bans: Viramontes, Grant, and the Road to a 2027 Decision
On the last day of its 2025–2026 term, the Supreme Court of the United States did something it had declined to do for years. It agreed to decide whether the Second and Fourteenth Amendments protect the right to possess AR-15-platform rifles and similar semiautomatic firearms. The vehicle is a pair of consolidated cases: Viramontes v. Cook County, No. 25-238, from the Seventh Circuit, and Grant v. Higgins, No. 25-566, from the Second Circuit. The question presented is spare and deliberate: “Whether the Second and Fourteenth Amendments guarantee the right to possess AR-15 platform and similar semiautomatic rifles.”
That question has hovered over American firearms law since District of Columbia v. Heller in 2008. Heller held that the Second Amendment protects an individual right to keep and bear arms and that the government may not ban an entire class of arms “in common use” for lawful purposes. It also said that “dangerous and unusual” weapons fall outside that protection. Handguns, the Court held, are in common use. Machineguns, it suggested, are not. What the Court never squarely answered is where the most popular rifle in the country sits on that line.
For more than a decade, states and localities filled the silence with “assault weapon” statutes. Cook County, Illinois, and the State of Connecticut are two of the jurisdictions that did so. Their laws ban, by name and by feature, the AR-15 and a long list of similar rifles. Lower federal courts, applying Heller and later New York State Rifle & Pistol Association v. Bruen, repeatedly upheld those bans. On June 30, 2026, the Supreme Court granted review and consolidated the two petitions for one hour of argument. The cases are now on the October Term 2026 docket. A decision is expected by the end of that term—June 2027.
The most immediate development is the petitioners’ merits brief, filed August 28, 2026. That filing, together with an early amicus brief the day before, marks the start of the merits stage. Respondents’ briefs are due October 21, 2026. Reply briefing follows in November. Argument will come later in the term. What the Court says in 2027 will not merely dispose of two local bans. It will tell every legislature and every court of appeals whether America’s most common civilian rifle is a constitutional “arm” or a category of weapon that may be outlawed because officials prefer something else.
The Cook County Ordinance and the People Who Challenged It
Cook County’s ban did not begin as a statewide project. It began as a local ordinance, adopted in 2006 and later expanded, that prohibits the possession, sale, and transfer of what the county labels assault weapons. The code names more than one hundred specific rifles, including AR-15 and AK-47 platforms. It also reaches any semiautomatic rifle that can accept a magazine holding more than ten rounds and that has at least one listed physical feature—a folding or telescoping stock, a pistol grip, a barrel shroud, a flash suppressor, or a similar characteristic. A first offense can bring up to six months in jail and a minimum fine of $5,000.
The ordinance is not a relic. It was the local precursor to Illinois’s later statewide Protect Illinois Communities Act, which copied much of the same list and feature test. Residents of Cook County who want a rifle that is legal in most of the United States cannot buy one, keep one, or take lawful title to one without violating county law.
Cutberto Viramontes is one of those residents. He wants an AR-15-style rifle for self-defense. Christopher Khaya wants an IMI Galil, another semiautomatic rifle on the banned list. They did not sue alone. They joined the Firearms Policy Coalition and the Second Amendment Foundation and filed in the Northern District of Illinois in August 2021. The suit sought declaratory and injunctive relief and, importantly for later mootness analysis, nominal damages. After the district court granted summary judgment to the county in March 2024, the Seventh Circuit affirmed in a short order on June 2, 2025. The Supreme Court then granted certiorari.
The procedural history matters because the Seventh Circuit did not write on a blank slate. In 2023, in Bevis v. City of Naperville, a panel of that court upheld Illinois and local assault-weapon bans at the preliminary-injunction stage. The majority reasoned that AR-15s are “indistinguishable” from M16s, more useful in military service than for civilian self-defense, and therefore outside the Second Amendment’s definition of “arms.” When Viramontes arrived on a fuller record, the court said the plaintiffs had not developed facts sufficient to escape Bevis. The ban stood. That is the judgment now before the Supreme Court.
Connecticut’s Statute and Grant v. Higgins
Connecticut’s law is a state felony statute rather than a county ordinance, but the design is familiar. After the Sandy Hook murders, the legislature banned a set of semiautomatic centerfire rifles by name and by feature. The current version reaches rifles that accept a detachable magazine and have at least one listed characteristic: a folding stock, a pistol grip, a forward pistol grip, a flash suppressor, or a fixed magazine holding more than ten rounds, among others. Possession of a covered rifle acquired after April 3, 2013, is a crime.
Eddie Grant Jr., Jennifer Hamilton, Michael Stiefel, the Connecticut Citizens Defense League, and the Second Amendment Foundation challenged that statute. The district court denied a preliminary injunction. On August 22, 2025, the Second Circuit affirmed. Unlike the Seventh Circuit, the Second Circuit assumed without deciding that the rifles were “arms.” It then applied a relaxed historical inquiry, citing the “unprecedented societal concern” of mass shootings, recast Heller’s phrase “dangerous and unusual” as “unusually dangerous,” and upheld the ban because the state still allowed other firearms that the legislature deemed less dangerous for self-defense.
The Grant petition asked whether the Second and Fourteenth Amendments guarantee the right to possess semiautomatic rifles “in common use for lawful purposes, including the most popular rifle in the country, the AR-15.” When the Supreme Court granted both petitions on June 30, 2026, it limited review to the question presented in Viramontes and consolidated the cases. Future filings appear on the Viramontes docket. One hour of argument will cover both.
Taking two cases rather than one was a structural choice. In 2020, after the Court granted review in New York State Rifle & Pistol Association v. City of New York, the city and state rewrote the challenged transport rule. The Court dismissed the case as moot. Justice Kavanaugh concurred but warned that lower courts were not faithfully applying Heller and McDonald. Two years later came Bruen. Mootness is far less available here. Cook County is unlikely to legalize AR-15s to escape a ruling. Connecticut is unlikely to repeal a post-Sandy Hook statute for the same reason. The Viramontes complaint also pleaded nominal damages, a claim that survives repeal of the ordinance itself. Two independent bans in two circuits make it much harder for a single legislature to pull the case out from under the Court.
Heller, Bruen, and the Fight Over Method
Any honest account of these cases has to start with method, because method is what the governments and the challengers are really fighting about.
Heller held that the Second Amendment’s operative clause—“the right of the people to keep and bear Arms, shall not be infringed”—protects an individual right unconnected to militia service. The prefatory militia clause announces a purpose; it does not confine the right. The Court then asked which arms the right covers. It looked to the historical tradition of banning only “dangerous and unusual” weapons and protecting arms “in common use at the time” for lawful purposes such as self-defense. Handguns qualified. The District of Columbia’s handgun ban did not.
McDonald v. City of Chicago applied that holding to the states through the Fourteenth Amendment. Bruen rejected means-end balancing. If the Second Amendment’s plain text covers an individual’s conduct, the government must justify its regulation by demonstrating that it is consistent with the Nation’s historical tradition of firearm regulation. Bruen was a carry case, not a ban-on-a-class-of-arms case. Heller remains the Court’s last word on which weapons may be banned outright.
Petitioners say that distinction is decisive. A ban on a type of firearm is governed by Heller’s common-use test. Courts do not get to invent a new historical analogical exercise that treats popularity as irrelevant and “military usefulness” as disqualifying. Respondents say common ownership is not enough. Some argue that “common use” belongs inside the threshold textual inquiry and that “arms” already incorporates Heller’s limitations. Others argue that common use requires proof of actual use in self-defense, not mere sales figures, and that a weapon useful for “offensive combat” is not the sort of arm the Amendment protects. The National Association of Attorneys General’s summary of the grant captured that split cleanly: Cook County wants common use treated as a textual limit; Connecticut wants an analysis of “actual use and functionality for self-defense—not its popularity in the abstract.”
That methodological fight explains why the Court took the cases now. After Bruen, every court of appeals to reach a so-called assault-weapon ban on the merits has upheld it. The First, Second, Fourth, and Seventh Circuits have done so on varying theories. There is no classic circuit split in outcome. There is a deepening split in reasoning, and a growing pile of petitions asking the Court to say whether Heller still means what it said. The grant on June 30 ended that period of denial.
The August 28 Brief: What Petitioners Asked the Court to Hold
On August 28, 2026, Cooper & Kirk filed the opening merits brief for all petitioners. David H. Thompson is counsel of record. Peter A. Patterson, William V. Bergstrom, and J. Joel Alicea appear with him. Connecticut counsel Craig C. Fishbein appears for the Grant plaintiffs. The same day, the parties filed the joint appendix. A day earlier, attorney G. Antaeus B. Edelsohn filed an amicus brief pressing the militia-arm argument. Those three filings are the first complete merits-stage papers the Court has seen in an AR-15 ban case.
The brief’s structure tracks Heller. First, the plain text. Semiautomatic rifles are arms. The Second Amendment’s text covers “Arms,” not “handguns only” and not “arms that a legislature finds suitable for home defense.” The Seventh Circuit’s holding that Cook County’s ban does not even implicate the text is, petitioners argue, irreconcilable with Heller. If a firearm is not an “arm” because a county board says it is too effective, then the Amendment’s operative language has been rewritten.
Second, history and common use. AR-15-platform rifles have been sold to American civilians since the 1960s. They are legal in the large majority of states. They are, by every serious count, the most popular rifles in the country. Petitioners and supporting groups have long analogized their numbers to ordinary consumer goods—SAF’s Adam Kraut observed after the grant that it is hard to argue that a rifle type that may outnumber Ford F-150s fails a common-use test. The brief treats that popularity as legally sufficient under Heller. A weapon that is unusual may be banned. A weapon that is common may not be banned because officials dislike its appearance or its rate of semiautomatic fire.
Third, the governments have the militia clause backward. Cook County and Connecticut have argued that AR-15s are not protected because they are useful for offensive combat rather than personal defense. Petitioners answer that the Amendment’s prefatory clause identifies a well-regulated militia as necessary to the security of a free state. An arm does not lose protection because it is suitable for that purpose. If anything, militia suitability cuts in favor of protection. The Edelsohn amicus pressed that originalist point at length, while drawing a line at fully automatic machineguns that the petitioners do not need the Court to erase in order to win. That line will be debated in commentary; it is not required by the question presented.
Fourth, the lower courts’ alternative formulations—“unusually dangerous,” “indistinguishable from the M16,” “unprecedented societal concern”—are not the test Heller announced. Handguns are used in the overwhelming majority of firearm homicides. Heller still protected them as a class. Long guns of all types account for a much smaller share of homicides. Treating the most common civilian rifle as uniquely ban-able because of rare, horrific crimes inverts the Court’s own hierarchy. Petitioners also note that justices across the Court’s ideological range have already described these rifles in ordinary-consumer terms. Justice Kagan, writing for a unanimous Court in Smith & Wesson Brands, Inc. v. Estados Unidos Mexicanos in 2025, called the AR-15 “widely legal and bought by many ordinary consumers.” Justice Sotomayor, dissenting in Garland v. Cargill, called them “commonly available, semiautomatic rifles.” Those descriptions are not holdings, but they undercut the claim that the rifles are exotic military instruments unknown to the civilian market.
The brief does not ask the Court to invent a new right. It asks the Court to apply the right Heller already recognized to the rifle Heller never had occasion to name.
What Comes Next on the Calendar
The Clerk granted an agreed briefing extension on July 15, 2026. Petitioners’ brief and the joint appendix were due August 28. Respondents’ merits briefs are due October 21. The reply is due November 20. That schedule was designed, counsel told the Clerk, to permit argument in the December or January sitting and to accommodate trial and other obligations. One hour is allotted. No argument date has been announced.
Observers who count grants on the October Term 2026 docket have placed these cases well into the sequence of argued matters. Chief Justice Roberts has typically scheduled about nine arguments per monthly sitting. On that pattern, argument in early December 2026 is a reasonable projection. Opinions in high-stakes cases argued that late in the calendar year often arrive in June. A decision in the final week of June 2027 would fit the Court’s ordinary end-of-term practice. Those dates are estimates, not orders. The Court can accelerate or delay. What is fixed is the term: October Term 2026, with a decision expected in 2027.
Amicus practice will be heavy. Gun-rights organizations, state attorneys general, historians, and social-science filers will all appear. Watchers have asked whether the Solicitor General will file in support of petitioners and whether experienced Supreme Court counsel such as Paul Clement and Erin Murphy will file an amicus that the justices read with particular care. There is no federal analogue to these bans, so the United States has no statute of its own to defend. The administration’s recent Second Amendment posture makes a supporting brief plausible. None of that is on file yet. The only merits brief that exists as of late August 2026 is the petitioners’.
Why Two Circuits and a National Map Matter
Fourteen states and the District of Columbia have enacted comparable laws. Some ban rifles by name. Some use feature tests that turn a legal rifle into a felony the moment a pistol grip or adjustable stock is attached. Some combine both. Illinois built a statewide ban on the Cook County model. California, New York, Maryland, New Jersey, Massachusetts, and others have their own versions. Challenges to those laws are pending or stayed in multiple circuits. The Ninth Circuit already delayed argument in a long-running challenge to California’s assault-weapons ban so it can await Viramontes and Grant. A Virginia district court was asked to stay related proceedings for the same reason. Whatever the Supreme Court writes will not stay confined to Chicago and Hartford.
A holding that AR-15-platform rifles are arms in common use would not automatically invalidate every magazine limit, every feature restriction, or every licensing rule. The question presented is possession of the rifles themselves. Courts would still have to apply Bruen to regulations that fall short of a ban. But the central theory used to sustain these statutes—that the rifles are not “arms” at all, or that they may be banned because they resemble service rifles—would be gone. Legislatures that built their codes on that theory would have to start over.
A holding that the bans are consistent with history would, by contrast, give states a clear green light. It would also invite a new generation of lists: more named models, more features, more arguments that the next popular rifle is “too military.” That is why the methodology paragraph in the eventual opinion may matter as much as the disposition. Commentators already worry that a unanimous judgment purchased with softening language would be worse for future cases than a narrower majority that keeps Heller’s common-use rule intact. That is prediction, not law. The Court has not spoken.
The Human and Civic Stakes
It is easy to discuss these cases as abstractions—docket numbers, feature tests, analogical history. The plaintiffs are not abstractions. They are people who live in jurisdictions where a rifle that is ordinary in Indiana, Texas, Florida, or most of rural America is contraband. They want the same tool for home defense, competition, and lawful recreation that their fellow citizens already own in the tens of millions. The organizations that joined them exist to make that claim in court when individual owners cannot bear the cost alone.
Governments on the other side point to mass shootings in which some of these rifles were used. Those crimes are real. The legal question is not whether they are tragic. The legal question is whether the Constitution permits a state or county to ban an entire class of commonly owned arms because a subset of criminals misuse them. Heller answered that question for handguns. Viramontes and Grant ask whether the answer is different for rifles.
There is also a federalism and notice problem. A rifle legal in most of the country becomes a jail sentence a few miles across a county line. Travelers, heirs, and people who move for work discover that a firearm they purchased lawfully is suddenly an “assault weapon.” Feature tests are especially unstable. A stock, a grip, or a muzzle device can change the legal status of an otherwise identical gun. If the Supreme Court holds that the underlying rifle is protected, many of those tripwires lose their justification.
What to Watch Between Now and Judgment Day
Several markers will tell observers how the case is developing. First, the respondents’ October briefs: do they double down on the claim that these rifles are not “arms,” or do they retreat to a narrower historical-analogue argument that assumes the text is satisfied? Second, the Solicitor General: silence, a brief supporting neither side, or an affirmative brief for the Second Amendment. Third, the argument date and the composition of the bench that hears it. Fourth, whether any jurisdiction attempts a last-minute amendment to manufacture mootness—an effort the nominal-damages claim and the dual-case structure are designed to defeat.
Fifth, collateral litigation. Illinois’s statewide ban, California’s statute, magazine cases, and 18-to-20-year-old purchase cases are all moving on nearby tracks. The Court denied several young-adult petitions around the same time it granted these rifle cases. Those splits will linger until the Court is ready. A 2027 opinion on AR-15s will not resolve every Second Amendment dispute. It will resolve the one that lower courts have used to treat the country’s most common rifle as if Heller never spoke.
Conclusion
Viramontes v. Cook County and Grant v. Higgins are not technical follow-ons to Bruen. They are the Court’s first direct engagement with the question Heller left on the table: may the government ban the AR-15? The petitioners’ August 28, 2026 brief gives the justices a complete merits argument built on text, common use, and the militia purpose the Amendment itself announces. The governments will answer in October. Argument will follow. By June 2027, there should be an opinion.
Until that opinion issues, the law remains what the Seventh and Second Circuits said it was: these bans stand. After that opinion issues, either they will not, or the Supreme Court will have told the country that the most popular rifle in America may be treated as contraband. That is the choice the Court granted certiorari to make. The briefing has begun. The 2027 decision will finish it.
