Bring Your Firearms the Legal Way and Sleep Easy

This is general information, not legal advice. California firearm law changes often and several parts are in court right now. Before you move, confirm your own situation with the California Department of Justice Bureau of Firearms and with your base legal office. NBVC Force Protection sets the rules for the installation.

California has some of the strictest firearm laws in the country. Most service members can bring most of what they own. A few common items cannot cross the state line at all, and it is far easier to deal with those at your old duty station than at the border.

The assault weapon test. The law names some models outright. It also covers any semiautomatic centerfire rifle without a fixed magazine that has even one of these: a pistol grip, a thumbhole stock, a folding or telescoping stock, a flash suppressor, a forward pistol grip, or a grenade or flare launcher. A fixed magazine over 10 rounds, or an overall length under 30 inches, also qualifies. Many standard AR and AK pattern rifles meet the test as they come from the factory.

Your options. Store the firearm or magazines out of state with family or a licensed dealer. Sell them before you move. Or have a gunsmith change the firearm so it no longer meets the definition before it enters California.

There is a narrow Military Assault Weapon Permit from the Department of Justice. It applies only to weapons used in military sanctioned activities and needs a letter from your base commander, so it does not cover a personal collection.

A federal court case over the assault weapon law was paused in July 2026 while the Supreme Court considers related cases. The magazine limit was upheld by the Ninth Circuit in March 2025 and a further appeal is pending. Both laws are in force today.

Someone who moves to California with firearms is a "personal firearm importer" under state law. Within 60 days that person must do one of three things: report the firearms to the Department of Justice, sell or transfer them through a licensed dealer, or turn them in to law enforcement.

The report is the New Resident Report of Firearm Ownership, form BOF 4010A. You can file online through the state's firearm reporting system. It covers handguns and long guns. There is a fee per report, so check the current amount.

The military wrinkle. The Penal Code says that for this rule a service member's residency is established when they are discharged in California. That suggests active duty members on orders may not have to report until then. The state's form still accepts military filers with a military ID and PCS orders. Ask your base legal office, and think about filing anyway. A report on file makes buying ammunition simpler.

A home built firearm without a serial number needs a state serial number application within 60 days.

• Handguns ride unloaded and locked in the trunk or in a locked container. The glove box and the center console do not count.
• Long guns ride unloaded. A locked case is the smart choice.
• Leaving a handgun in an unattended vehicle means locking it in the trunk or in a locked container out of sight.
• Passing through other states, federal law protects travelers who keep firearms unloaded and out of reach, where you may lawfully possess them at both ends of the trip.
• Shipping with household goods is usually allowed. Tell your transportation office what you are shipping and follow its rules. Ammunition does not go on the truck.

The border stations on the highways into California are agricultural checkpoints. They ask about fruit and plants.

Since January 1, 2026, state law requires firearms in a home to be stored securely when you are not carrying them or keeping them within reach. That means a locked safe or a Department of Justice approved locking device. Plan for a safe in your new place.

• Register personal firearms with NBVC Security, through Force Protection, when you arrive. Headquarters is Building 1443 at Port Hueneme. The Point Mugu precinct is Building 613.
• Barracks residents store weapons in the armory, not in the room.
• In family housing, keep the weapon and the ammunition locked up separately.

Base rules can change with the commanding officer. Call Force Protection before you bring a firearm through the gate, and ask your sponsor to confirm what your command expects.

Living off base keeps you under state law alone. Your landlord or homeowners association may have its own rules. If you would rather own your walls, start with a pre-approval.

• You can buy as an active duty member with a military ID and PCS orders that show a California duty station.
• The Firearm Safety Certificate is waived for active duty, reserve and honorably retired members.
• Every purchase has a 10 day wait.
• The limit is three firearms in any 30 days, as of April 2026.
• Handguns sold by dealers must be on the state roster. That applies to dealer sales, not to handguns you already own.
• An 11 percent state excise tax applies to firearms and ammunition.
• Ammunition takes a background check every time. The low cost check works only if the state has a firearm record in your name.
• Ammunition bought out of state generally has to come in through a licensed California vendor.

California does not honor any other state's carry permit. A license comes from the county sheriff or city police and takes 16 hours of training. Since January 1, 2026, people who are not California residents can apply. Open carry is banned in most places. The list of places where carry is off limits is long and partly in court.
