Illinois and Connecticut Defend AR-15 Bans Before Supreme Court
Cook County, Illinois, and the State of Connecticut filed opening briefs at the U.S. Supreme Court defending their bans on commonly owned semi-automatic rifles, including the AR-15. The filings respond to two challenges brought by the Second Amendment Foundation, which the justices agreed to hear this summer. The cases, Viramontes v. Cook County and Grant v. Higgins, are set for oral argument on Wednesday, December 2. The government briefs released October 22 lay out why the states believe their laws meet constitutional standards. The Court has not yet ruled on the merits of a modern rifle ban, so these arguments could set the rule for dozens of state and local prohibitions.
Key Details
The filings and the case posture break down into a few concrete facts:
- Viramontes v. Cook County was filed in 2021. It targets Cook County's ban on many commonly owned modern firearms.
- Cook County's ordinance served as the template for the nearly identical statewide ban the Illinois legislature passed later.
- Grant v. Higgins challenges Connecticut's ban on commonly owned semi-automatic rifles. SAF attacks the law both by name and by its feature list.
- The Firearms Policy Coalition and two private citizens join SAF in Viramontes. The Connecticut Citizens Defense League and three private citizens join SAF in Grant.
- Oral arguments in both cases are scheduled for December 2, 2026.
- SAF Executive Director Adam Kraut says the bans single out rifles over features like stock adjustability and grip angle. He argues the Court's existing framework already rejects these laws.
- SAF founder and Executive Vice President Alan M. Gottlieb points to Supreme Court language protecting arms in 'common use' and cites more than 30 million owners of the targeted rifle.
- SAF says it will file a reply brief responding to the government positions before argument.
Background
The fight traces back to District of Columbia v. Heller in 2008. That decision struck down a handgun ban and said the Second Amendment protects arms in common use for lawful purposes. Justices have leaned on that 'common use' language ever since, and it sits at the center of SAF's argument. Illinois and Connecticut built their rifle bans after mass shootings. Connecticut passed its law in 2013 following the Sandy Hook school shooting. Illinois lawmakers passed the statewide ban in 2023, after the Highland Park Fourth of July parade shooting in 2022. Cook County's ordinance came first.
The legal test shifted in 2022. In New York State Rifle & Pistol Association v. Bruen, the Court ruled that gun laws must match the nation's historical tradition of firearm regulation. Governments must point to historical analogues. Viramontes was filed before Bruen rewrote the framework, so the case now runs through a standard the Court created after the complaint was filed. That timing gives the states a harder path than they had when they wrote their laws. The Court's next decision will show how strictly it applies Bruen to modern rifles.
Why It Matters for Gun Owners
Illinois and Connecticut residents face the immediate impact. Both states restrict the sale and possession of many semi-automatic rifles built around detachable magazines and specific features such as pistol grips, folding or telescoping stocks, and flash suppressors. Owners in those states need to know exactly what their rifles contain and whether their existing guns fall under grandfather or registration provisions. A feature-based definition can turn a minor parts change into a legal violation, so any rifle upgrade in those states deserves a check against the current statute.
Gun owners outside those states should still pay attention. A ruling that upholds categorical bans would give legislators in other states a clear template, and a ruling that strikes them would weaken dozens of existing laws. Watch the December 2 argument for how the justices handle the 'common use' question and the historical analogues the states offer. Read the state briefs directly. Keep receipts and transfer records for any firearm you own, and avoid moving rifles across state lines without checking the law in every state you pass through.
DownRange Analysis
Do these bans survive Bruen? The states will lean on historical laws that regulated dangerous weapons. Their best argument is that modern rifles are more lethal than the arms of 1791 and that the bans fit a tradition of regulating dangerous and unusual weapons. The problem is that Heller framed the protected class around common use, not around how a weapon looks or what features it carries. An AR-15 sits in millions of American homes. Any court that accepts the states' framing needs to explain why a rifle used by that many lawful owners falls outside the right. Expect the justices to press that gap hard on December 2.
The market will react to whatever the Court does. Rifle demand has spiked after past ban headlines, and prices follow the panic, not the law. Do not buy in a rush because a brief dropped. Do this instead: confirm your rifle's legal status in your state, keep your paperwork in order, and support the litigation through SAF, FPC, or CCDL if you can. Contact your state legislators now, because the next ban will follow whatever this Court decides.
