Gunmakers Join GOA's AR-15 SCOTUS Fight

Gun Owners of America just recruited four major manufacturers to tell the Supreme Court that AR-15s are constitutionally protected—not negotiable.

State of play: GOA and Gun Owners Foundation filed an amicus brief Wednesday in Viramontes v. Cook County, joined by Century Arms, Canik USA, B&T USA and Fostech. The question before the Court is blunt: does the Second Amendment protect Americans' right to own AR-15s and similar semiautomatic rifles?

• The scale: An estimated 20 to 40 million AR-15s are in American hands, making them the best-selling rifle platform in the country.
• The legal hook: The Court has already acknowledged in prior rulings that these rifles are "in common use"—a standard that matters a lot in Second Amendment litigation.
• The lineup: This isn't just an advocacy group talking theory. It's the people who actually build these rifles telling the justices how they work and why.

The manufacturers aren't mincing words. Ridley Key, CEO of B&T USA, put it plainly: the features that gun-control laws single out—pistol grips, adjustable stocks, standard-capacity magazines—are the same features that make a rifle safer and easier to control. Adam Ruonala of Century Arms and Canik USA called the case a "historic opportunity" to settle the question for good. Fostech co-founder David Foster framed it in even starker terms, invoking natural-rights language that goes beyond legal briefs into first principles.

"The right to keep and bear arms does not belong to any government. It is God-given—endowed by our Creator, not granted by man." — David Foster, Fostech

The legal argument: GOA's brief rejects the idea that the Constitution distinguishes between "civilian" and "military-style" weapons. The brief leans on founding-era history—the Founders expected citizens to own the same class of arms as soldiers, not a watered-down civilian tier. If the Court buys that framing, it undercuts the entire premise behind state "assault weapons" bans, which typically target rifles based on cosmetic features rather than function.

The intrigue: This brief isn't just GOA vs. Cook County. It's four companies whose product lines depend on the outcome putting their names on the record, publicly, in a case that could reshape gun law in states like California, New York, Illinois and New Jersey. That's a level of industry exposure you don't see in every Second Amendment case.

What to watch: The Supreme Court hasn't yet granted certiorari to hear Viramontes on the merits—this filing is aimed at persuading the justices the case deserves full review. If cert is granted and the Court rules that AR-15-pattern rifles are protected arms in common use, GOA's Erich Pratt says states with existing bans will face "a reckoning like never before." Owners in ban states should treat this as a case to track closely, not a done deal—the Court could still decline review or rule narrowly.
