Third Circuit Strikes Down New Jersey's Assault-Weapons and Magazine Bans

A divided en banc Third Circuit ruled on July 17, 2026 that New Jersey's bans on semi-automatic assault firearms and magazines holding more than 10 rounds violate the Second Amendment, the first time a federal appeals court sitting en banc has struck down a state assault-weapons ban. The ruling is not yet in effect.

Jurisdiction scope: This article addresses a Third Circuit ruling on New Jersey's firearms statutes under the Second Amendment. The Third Circuit covers New Jersey, Pennsylvania, Delaware, and the U.S. Virgin Islands, but this decision concerns New Jersey law. It is not legal advice, and because the ruling is not yet in effect, it does not change what is legal to own today. For related coverage, see our overview of New Jersey self-defense laws.

What Happened

On July 17, 2026, the U.S. Court of Appeals for the Third Circuit, sitting en banc, held 10-5 that two New Jersey firearms laws violate the Second Amendment: the state's ban on semi-automatic assault firearms and its ban on magazines that hold more than 10 rounds. Judge Arianna J. Freeman wrote the majority opinion in Association of New Jersey Rifle and Pistol Clubs v. Attorney General New Jersey, No. 24-2415, consolidated with related challenges. Judge Patty Shwartz wrote the principal dissent.

Applying the Supreme Court's framework from New York State Rifle and Pistol Association v. Bruen, the majority held that semi-automatic rifles such as the AR-15 and magazines exceeding 10 rounds are in common use for lawful purposes and are therefore presumptively protected. The court found that New Jersey failed to identify a historical tradition of banning commonly owned arms, writing that the state's proffered historical analogues were "too late in time, and none enacted an outright ban on a class of weapons in common use for lawful purposes." The en banc court went further than the district court, which had struck the ban only as applied to the Colt AR-15, extending the holding to the class of semi-automatic rifles the statute sweeps in and separately invalidating the magazine cap.

The dissent disagreed sharply. As Judge Shwartz put it, in the dissent's view "AR-15s are not arms that the Second Amendment protects, and the state may ban them."

What the Law Actually Says

The Second Amendment analysis here runs through two Supreme Court decisions. District of Columbia v. Heller, 554 U.S. 570 (2008), recognized an individual right to keep and bear arms and protected weapons in common use. Bruen, decided in 2022, directed courts to ask whether a regulation is consistent with the nation's historical tradition of firearm regulation, rather than balancing interests. The Third Circuit majority applied that test and concluded New Jersey could not meet it for either ban. How firearm and self-defense rules vary by state is the subject of our guides to New Jersey self-defense laws and the broader self-defense law overview.

The timing is the part most likely to be misunderstood. A ruling being issued is not the same as a ruling taking effect. New Jersey has a window, reported as running to roughly July 31, 2026, to ask the full court to rehear the case, and the court's formal mandate directing the lower court to act is expected around mid-August. The state Attorney General's office has pointed to early August as a possible effective date if no rehearing is sought. No stay and no Supreme Court petition had been reported as of July 25, 2026. Until the mandate issues, New Jersey's existing assault-firearm and large-capacity-magazine statutes remain on the books.

The ruling also sharpens a genuine split among the federal appeals courts. Just eight days earlier, on July 9, 2026, the Seventh Circuit upheld a comparable Illinois ban. The Supreme Court had already agreed, before the Third Circuit ruled, to hear cases from that Illinois line, Viramontes v. Cook County and Grant v. Higgins, on whether AR-15-type rifles are protected arms, with argument expected in the fall 2026 term. Those cases, not this New Jersey one, are the vehicles now before the justices. Illinois readers can compare their own rules in our guide to Illinois self-defense laws.

Analysis: Why This Matters

The following is analysis from the Recording Law Editorial Team.

The doctrinal significance is real: this is the first time a federal appeals court sitting en banc has struck down a state assault-weapons ban, and it did so on both the rifle ban and the magazine cap. But the practical significance for New Jersey residents today is limited, because the ruling is not in effect. The most common error in coverage of decisions like this is to treat the day of the opinion as the day the law changes. Here, the rehearing window, the mandate schedule, and any request for a stay all sit between the opinion and any change on the ground.

The larger story is the split. With the Third and Seventh Circuits now openly disagreeing, and the Supreme Court already set to hear the question from the Illinois side, the durability of this ruling depends on what the justices do. We take no position on how that will come out. The vote itself resists easy labels, with a judge appointed by a Democratic president writing the majority and a mixed group in dissent, which is worth noting as fact rather than prediction.

How This Affects You

For New Jersey gun owners, the key takeaway is that nothing about what is legal to own or buy has changed as of July 25, 2026. The state's assault-firearm and magazine statutes remain enforceable until the court's mandate issues or a further order says otherwise, and the exact effective date is still unsettled. Anyone making decisions based on this ruling should watch for the mandate and any stay, and should not assume the bans are void yet. This is general information, not advice about your situation.
