The U.S. Supreme Court has consolidated the cases Viramontes v. Cook County and Grant v. Higgins, which challenge bans on AR-15 and similar semiautomatic rifles in Cook County, Illinois, and Connecticut. These cases mark a critical juncture in Second Amendment jurisprudence and are attracting widespread legal attention.
As of early September 2026, there have been a record-setting 45 amicus briefs filed in support of the petitioners, reflecting intense advocacy from various legal and policy groups. The volume of briefs signals the case's importance in shaping future firearms regulation across the country.
Among the notable amicus filings is the brief from the U.S. Solicitor General, submitted on September 4, 2026, which argues that AR-15 bans are unconstitutional. The brief states, "The AR-15 rifle is unquestionably in common use among law-abiding citizens for lawful purposes," asserting its protected status under the Second Amendment. This position aligns with key arguments from previous Supreme Court rulings such as District of Columbia v. Heller (2008) and New York State Rifle & Pistol Association v. Bruen (2022).
The National Rifle Association (NRA), alongside the Independence Institute and the American Suppressor Association, filed an amicus brief on September 5, highlighting that modern semiautomatic rifles are the product of centuries of firearm technology development. The NRA emphasized the rifles’ historic and lawful nature, countering the bans’ labels.
Support also comes from groups like the Indiana State Rifle & Pistol Association (ISRPA), which announced its participation in the amicus effort on August 26, underscoring the case’s statewide and national significance for gun owners.
Legal professionals and policymakers should closely watch this case, as its outcome could recalibrate the boundaries of permissible gun regulation and shape debates on constitutional rights.
By the numbers:
- 45 amicus briefs — filed as of early September 2026 supporting AR-15 ban challenges
- September 4, 2026 — U.S. Solicitor General filed an amicus brief opposing AR-15 bans

What's next: The Supreme Court’s schedule for hearings has not yet been announced, but the ruling will be pivotal for nationwide gun policy.
