New Jersey's Assault Weapons Ban Struck Down: What it Means for Gun Owners

Key Takeaways

• On July 17, 2026, the full Third Circuit Court of Appeals ruled that New Jersey may no longer ban semi-automatic rifles like the AR-15 or standard magazines that hold more than ten rounds. The court held these are firearms and magazines in “common use” by millions of law-abiding Americans, and there is no historical tradition that supports banning them.

• This does not mean it is suddenly open season to go buy an AR-15 or a 15-round magazine. The case was sent back to the lower court; the New Jersey Attorney General is “considering her options,” and the U.S. Supreme Court is about to weigh in on nearly identical bans. The law is changing by the week.

• The ruling affects two of the most serious gun statutes in New Jersey: unlawful possession of an assault firearm under N.J.S.A. 2C:39-5(f), a second-degree crime, and possession of a large-capacity magazine under N.J.S.A. 2C:39-3(j).

A Major Shift in New Jersey Gun Law

For more than three decades, New Jersey has had some of the strictest gun laws in the country. Two of them stood out. You could not legally possess an “assault firearm,” and you could not possess a magazine that held more than ten rounds. Violate either of these statutes, and you were not looking at a ticket. You were looking at an indictable charge (aka Felony), and in many cases, mandatory prison time.

That changed on July 17, 2026. In a 10-5 decision, the Third Circuit Court of Appeals struck down both bans as unconstitutional. If you own firearms in New Jersey, are facing a weapons charge, or have a conviction on your record, you need to understand what this ruling does, what it does not do, and what you should actually do next.

What the Third Circuit Actually Decided

The case is Association of New Jersey Rifle & Pistol Clubs v. Attorney General of New Jersey. Writing for the majority, Judge Arianna Freeman held that New Jersey’s complete prohibition on possessing semi-automatic rifles “runs afoul of the Second Amendment’s protections,” and that the state’s limits on large-capacity magazines fail for the same reason.

The court applied the framework the Supreme Court laid out in New York State Rifle & Pistol Association v. Bruen and District of Columbia v. Heller. Under that framework, if a weapon is in common use by ordinary people for lawful purposes, the government has to point to a historical tradition of regulating it. The court found that AR-15s and magazines holding more than ten rounds are owned by millions of Americans, and that no such historical tradition exists. As the majority put it, that is true “even when the regulations are passed with the intention of reducing gun violence.”

One important limit: the court ruled only on semi-automatic rifles. It specifically declined to decide the question for semi-automatic pistols and shotguns, finding the record did not contain enough evidence about those firearms. So the decision is broad, but it is not a blanket ruling that everything New Jersey once called an “assault firearm” is now legal.

Which New Jersey Laws Does This Affect

There are two statutes at the center of this:

Unlawful possession of an assault firearm (N.J.S.A. 2C:39-5(f)). This is a second-degree crime. A second-degree conviction in New Jersey carries 5 to 10 years in state prison, and assault firearm cases have

historically been prosecuted under the Graves Act, which requires a mandatory period of parole ineligibility (specifically, 3.5 years). In plain terms, this was one of the most dangerous charges a gun owner could face in this state.

Possession of a large capacity magazine (N.J.S.A. 2C:39-3(j)). New Jersey defines a large-capacity magazine as one capable of holding more than 10 rounds. Possessing one is a fourth-degree crime punishable by up to 18 months in prison. Thousands of otherwise law-abiding people were technically committing this offense simply by owning a magazine that came standard with their firearm.

The Third Circuit’s decision cuts directly against the constitutionality of both of these provisions as applied to semi-automatic rifles and standard magazines.

What This Means for You Right Now

A court striking down a law is not the same thing as that law disappearing overnight. Enforcement, appeals, and the practical reality on the ground all move at different speeds.

Should you run out and buy an AR-15 or a 15-round magazine?

Not so fast. The case was reversed in part and sent back to the trial court for a new order. The New Jersey Attorney General has already said her office is “considering its options,” which can include asking the Supreme Court to step in and potentially freezing this ruling while that plays out. Until the dust settles, buying or possessing one of these firearms or magazines could still put you at legal risk, and the rules can change again quickly. Do not make a decision that could cost you your freedom based on a headline.

What if you are currently charged with one of these offenses?

This ruling may be very good news for you. If you have a pending charge under N.J.S.A. 2C:39-5(f) or 2C:39-3(j) involving a semi-automatic rifle or a standard-capacity magazine, the constitutional ground under that charge has shifted dramatically. That is exactly the kind of development that can support a motion to dismiss or a much stronger negotiating position. But it has to be raised correctly, by someone who knows how to put this decision in front of the right judge at the right time.

What if you already have a conviction?

If you were convicted under one of these statutes, do not assume you are out of luck, and do not assume the record simply erases itself. There may be avenues worth exploring depending on where your case stands, but those options are fact-specific and time-sensitive. This is a conversation to have with an attorney, not something to guess at.

Why This Is Not the Last Word

This decision is historic. It is the first time a federal appeals court has invalidated a state assault weapon and large-capacity magazine ban, and it creates what lawyers call a circuit split, where different federal appeals courts have reached opposite conclusions on the same question. Splits like this one tend to get resolved in one place: the United States Supreme Court.

And the timing is no accident. Just weeks before this ruling, the Supreme Court agreed to hear challenges to assault weapon bans in Illinois and Connecticut. Whatever the Justices decide in those cases will likely control what happens in New Jersey. In other words, this fight is far from over. What is legal in New Jersey today may look different in a year, and anyone making decisions about firearms should treat the current moment as unsettled rather than final.

Why You Need an Experienced New Jersey Attorney

Rapidly changing law is where good lawyering earns its keep. A 192-page decision with a dissent, a partial reversal, and a remand is not a document the average person can turn into a defense. Knowing that a ban has been struck down is one thing. Knowing how to use it, whether it applies to your specific firearm, whether a stay is in place, and how a particular judge or prosecutor is treating it this week is another thing entirely.

That is what we do at Rosenberg Perry & Associates. We defend weapons charges throughout New Jersey; we track these rulings as they come down, and we know how to translate a shift in the law into a real advantage for the person sitting across from us.

Frequently Asked Questions

Is it legal to own an AR-15 in New Jersey now?

The Third Circuit has ruled that New Jersey cannot ban semi-automatic rifles like the AR-15, but the decision has been sent back to the lower court, and the state may ask the Supreme Court to intervene.

Until the situation is fully resolved, you should not assume possession is risk-free. Talk to an attorney before buying or possessing one.

Are 15-round magazines legal in New Jersey again?

The court struck down New Jersey’s ban on magazines holding more than 10 rounds. As with the rifle ruling, this is subject to further proceedings and possible Supreme Court review, so the safest course is to get current legal advice before you act on it.

I have a pending assault firearm or magazine charge. Does this help me?

It may help significantly. A ruling that the underlying law is unconstitutional can support a motion to dismiss or strengthen your negotiating position. The key is raising it properly and promptly, which is why you should have an experienced attorney review your case right away.

Does this ruling apply to handguns or shotguns?

No. The court limited its decision to semi-automatic rifles and declined to rule on semi-automatic pistols and shotguns because the record did not contain enough evidence about them. Do not assume other firearms are covered.

Could this ruling be reversed?

Yes. The New Jersey Attorney General is considering her options, and the Supreme Court has already agreed to hear similar cases from Illinois and Connecticut. The outcome of those cases could change the picture in New Jersey. This is an evolving area of law.
