Yes, AR-15 rifles are legal in California, but only when they are modified to comply with state assault-weapon rules. Many people believe the rifle itself is banned, but the law regulates the features on the rifle rather than the name “AR-15.” California does not outlaw the model; it outlaws certain combinations of characteristics that the state considers “assault-weapon features.” Because of this, the version of an AR-15 that you can legally own in California looks and functions differently than the rifles commonly sold in most other states. You can still buy one, shoot one, and legally own one, but its configuration must follow strict guidelines.
How California Defines an Assault Weapon

California does not ban the AR-15 by name. Instead, the state bans rifles that have both a detachable magazine and features such as a traditional pistol grip, adjustable stock, flash hider, or forward grip. Once a rifle has a detachable magazine paired with those features, it becomes an illegal “assault weapon” unless it was registered before the deadline years ago. Since registration for new assault weapons is closed, the only legal way to own an AR-15 now is to configure it so it does not meet the assault-weapon definition in the first place. That means the design and parts matter more than the brand stamped on the rifle.
What Makes a California-Compliant AR-15
There are two legal approaches. One is to build a “featureless” rifle. This type keeps its detachable magazine but removes any of the banned features, so the rifle remains legal without registration. A featureless AR-15 will often have a non-traditional grip shape, no flash hider, and a fixed-style stock. The other approach is to keep the normal features but change how the magazine works. California allows a rifle with those features only if the magazine is fixed in a way that it cannot be removed without partially disassembling the firearm first. That type of design slows reloading and changes how the rifle operates, but it keeps the gun legal for possession and sale.
Magazine Restrictions and Current Lawsuits
Even if the AR-15 is configured correctly, California still limits magazine capacity to ten rounds. Higher-capacity magazines remain illegal unless they were lawfully owned before older cutoff dates and properly registered. There is a major ongoing case, Duncan v. Bonta, which challenges the state’s magazine ban. Although the case has moved toward the U.S. Supreme Court, the Court has not yet agreed to hear it, so the ten-round restriction remains in effect. Until the Supreme Court intervenes, California residents cannot buy, sell, or import standard AR-15 magazines larger than ten rounds.
Buying and Owning an AR-15 in California
Purchasing a compliant AR-15 still requires following all standard California firearm procedures. Buyers must be at least 21 for most semi-automatic rifles, must pass a background check, must hold a Firearm Safety Certificate, and must wait ten days before taking the firearm home. California gun stores only sell rifles that already meet state compliance rules, so buying from a licensed retailer is the safest way to lawfully own one. Bringing a non-compliant rifle into the state, or converting a legal rifle into an illegal configuration, can result in felony charges.
Conclusion
AR-15 rifles are legal in California, but only because the state allows versions that avoid being classified as assault weapons. The rifle is not banned outright; the features are. A legal AR-15 must either remove the restricted features or lock its magazine in a way that prevents normal detachment. Owners must also follow the ten-round magazine limit and comply with California’s purchase and safety rules. In California, the difference between a lawful AR-15 and a criminal offense comes down to configuration, not the name on the firearm.
