In a landmark decision that reshapes the gun-rights landscape in one of the nation's most restrictive states, the U.S. Court of Appeals for the 3rd Circuit has struck down New Jersey's long-standing ban on so-called "assault firearms" and its cap on large-capacity magazines. The ruling, handed down by the full Philadelphia-based court sitting en banc, found that both restrictions violate the Second Amendment.

Background: New Jersey's Decades-Old Firearms Law

New Jersey's firearms regulations date back to 1990, when the state targeted "assault firearms," including AR-15 style semiautomatic rifles, by limiting their possession to individuals who obtained a specific state license. In practice, that licensing pathway proved illusory. No New Jersey resident had ever successfully obtained such a license, making it effectively impossible to legally possess those firearms in the state.

The magazine restrictions evolved over time as well. The state originally defined "large capacity" magazines as those holding more than 15 rounds, before tightening that threshold in 2018 to 10 rounds or fewer. That 2018 change prompted the Association of New Jersey Rifle & Pistol Clubs and two of its members to sue the state, arguing the tighter cap violated their Second Amendment rights.

The Ruling: A Sweeping 10-5 Decision

On Friday, July 17, 2026, the 3rd Circuit ruled 10-5 that New Jersey's ban on semiautomatic rifles and high-capacity magazines is unconstitutional, overturning decades of precedent in the state. The 192-page opinion, authored by Judge Arianna Freeman, consolidated three separate lawsuits challenging the law.

The court's reasoning leaned heavily on the framework the U.S. Supreme Court established in its 2022 Bruen decision, which requires modern gun regulations to be grounded in the nation's historical tradition of firearm regulation. The majority concluded that the firearms and magazines at issue are protected by the Second Amendment because they are in common use for lawful purposes, including self-defense, and that the state failed to identify a historical analog sufficient to justify the bans.

Notably, the appellate court went further than the district court below it. While a lower court had previously struck down the assault-firearm ban only as it applied to the AR-15, the 3rd Circuit expanded that holding to cover the entire class of semiautomatic rifles targeted by the law, and separately struck down the magazine capacity restriction as well.

The court also pointed to the sheer scale of ownership as evidence these firearms are in common use, noting that Americans lawfully possess at least 24 million AR-platform rifles nationwide.

Reactions From Both Sides

The decision, unsurprisingly, drew starkly different responses.

Gun-rights groups celebrated the outcome as a major milestone. Justin Davis, managing director of public affairs for the National Rifle Association, called it a monumental win in a case the organization had been litigating since 2018. Other advocacy groups, including the Firearms Policy Coalition, echoed that sentiment, framing the ruling as a strong signal ahead of anticipated Supreme Court review of similar laws in other states.

New Jersey officials, meanwhile, sharply criticized the decision. New Jersey Attorney General Jennifer Davenport called the ruling unfortunate and legally incorrect, noting that every other federal circuit court to consider similar bans had reached the opposite conclusion. Davenport further argued that assault weapons and large-capacity magazines contribute to the ongoing epidemic of mass shootings, and maintained that the state had acted reasonably in restricting them, while pledging that law enforcement would continue enforcing the state's other firearms laws.

Why This Case Matters Beyond New Jersey

The ruling adds to a growing list of gun restrictions falling in the wake of the Supreme Court's expansion of Second Amendment rights, under a test that requires states to point to historical analogues to justify modern gun-control measures. Because the decision breaks from rulings in other circuits that have upheld similar assault-weapon and magazine bans, legal observers widely expect the issue to eventually reach the U.S. Supreme Court.

For now, the 3rd Circuit's decision applies within its jurisdiction, which covers New Jersey, Pennsylvania, Delaware, and the U.S. Virgin Islands — meaning the immediate practical effect is concentrated in New Jersey, where the assault-firearm and magazine bans had been in place for over three decades.

What Happens Next

New Jersey officials have signaled they may pursue further appeal, and litigation over the case's remaining issues, including questions the appellate panel remanded back to the district court, is expected to continue. Given the circuit split this ruling creates, it is likely to become one of several test cases that could prompt the Supreme Court to weigh in directly on the constitutionality of state-level assault weapons and magazine bans.
