What States Have Banned AR-15 Rifles? A Guide to State Assault-Weapons Laws
When I started researching what states have banned ar 15 rifles, I expected a simple list. Instead, I found a patchwork of state statutes, feature tests, registration deadlines, magazine rules, and court challenges. In this article, I separate outright possession restrictions from laws that regulate certain configurations of the AR-15 platform.
I am focusing on the states with broad assault-weapons restrictions rather than pretending every AR-15 is treated identically everywhere. That distinction matters because a law can cover a semiautomatic rifle with a detachable magazine and specific features, while leaving another configuration under different rules. I would still verify the current text with a state attorney general, official legislative source, or licensed attorney before buying, transporting, or modifying a rifle.

what states have banned ar 15 rifles: What You Need to Know
My comparison identified a core group of states with laws that broadly restrict assault weapons, including many AR-15-style rifles: California, Connecticut, Delaware, Hawaii, Illinois, Maryland, Massachusetts, New Jersey, New York, Washington, and Vermont. Rhode Island also has an assault-weapons prohibition, and Colorado has enacted restrictions affecting certain semiautomatic firearms, so I would not treat this list as a substitute for checking the latest state text.
Why an AR-15 can be legal in one configuration and restricted in another
What surprised me most was how often the legal question turns on attributes rather than the name printed on the receiver. State laws may examine a detachable magazine, a pistol grip, adjustable stock, threaded barrel, flash suppressor, or other listed feature. Some statutes also identify models by name, while others use a parts-and-features test that reaches similar rifles.
The states where magazine rules and transport rules change the answer
I kept coming back to transport because ownership is only one part of the problem. A rifle that is lawfully possessed at home may still raise questions when I move it across state lines, bring it to a range, or store it in another residence. California, New York, New Jersey, Connecticut, Massachusetts, Maryland, and Illinois each require careful attention to combinations of assault-weapons rules, magazine limits, licensing, or transport provisions.
Grandfather clauses, registration deadlines, and prohibited transfers
A major source of confusion is the difference between keeping a covered rifle already lawfully possessed and acquiring one after a ban takes effect. Some states have used grandfather provisions or registration systems, while others impose tighter limits on inheritance, sale, lending, or movement. I found that the date of possession can matter almost as much as the rifle’s features.
How I would verify a state before buying or moving an AR-15
If I were making a decision today, I would use a short verification sequence rather than a nationwide chart. First, I would identify the state’s current definition of an assault weapon and compare it with the rifle’s exact model, magazine system, and listed features. Next, I would check whether the law covers possession, purchase, manufacture, transfer, transport, or only certain future acquisitions.
Frequently Asked Questions
What states have banned AR-15 rifles?
States with broad assault-weapons restrictions that can cover many AR-15-style rifles include California, Connecticut, Delaware, Hawaii, Illinois, Maryland, Massachusetts, New Jersey, New York, Rhode Island, Vermont, and Washington. Colorado also has significant restrictions affecting certain semiautomatic firearms. I would verify the current statute because coverage depends on model, features, dates, registration, and the specific conduct involved.
Are AR-15 rifles completely illegal in every state listed?
No. A state may prohibit new sales while allowing registered possession, or it may regulate only rifles meeting a specific feature test. Grandfather rules, registration deadlines, magazine limits, and exceptions can change the result. I would read the state’s definitions and operative sections instead of treating “ban” as a universal rule.
Can I transport an AR-15 through a state with an assault-weapons ban?
Possibly, but I would not assume that lawful ownership in your home state makes the trip lawful. The answer can depend on unloaded transport, locked containers, ammunition storage, destination, route, and whether the rifle itself is prohibited under local law. I would confirm the current transport statute and obtain legal advice for a multi-state trip.
Do these bans apply to every semiautomatic rifle?
Usually not. Many laws target a defined combination of a semiautomatic action, detachable magazine, named model, or listed features. Other semiautomatic rifles may fall outside the definition, while a rifle that looks different can still be covered by a copy-or-feature clause. The exact statutory wording matters more than the marketing name.
Can I modify an AR-15 to comply with a state law?
A modification may change whether a rifle meets a feature test, but I would treat that as a legal question rather than a hardware shortcut. Fixed magazines, featureless configurations, overall-length requirements, and magazine-capacity rules can interact differently by state. I would use current official guidance and a qualified attorney before assembling, buying parts for, or modifying the rifle.
Conclusion
After comparing the laws, my main takeaway is simple: there is no single national answer to what states have banned ar 15 rifles. The meaningful questions are whether the state regulates the exact configuration, whether possession was grandfathered, whether registration was required, and whether the planned purchase or transport is allowed. I would treat state assault-weapons law, magazine capacity, and transport rules as separate checks. If you are close to making a purchase or crossing a state line, I would pause and verify the current official rules rather than relying on an old chart or a retailer’s label.
