Buying a gun from a private party in Arizona is legal with no background check, no permit, and no state paperwork, provided both you and the seller are Arizona residents, you are not a prohibited possessor under federal law, you meet the age requirement, and the firearm itself is not restricted. The freedom is real, and so is the responsibility: the law puts the burden of a lawful transaction on you and the seller rather than on a government system.
What Arizona Law Requires of You
Arizona does not require a background check, a permit, or any form of registration when one private citizen sells a firearm to another. The state also bars cities and counties from adding their own registration or licensing rules, and political subdivisions cannot maintain lists of firearm owners, buyers, or sellers.1Arizona Legislature. Arizona Code 13-3108 – Firearms Regulated by State; State Preemption
That rule holds whether the sale happens in someone’s living room, a parking lot, or at a gun show. Licensed dealers at gun shows must still run background checks, but two private individuals who meet at a show can complete a sale without one.
Age Limits for a Private Purchase
In a private sale, you can buy any firearm in Arizona at age 18, including a handgun. Federal law prohibits transferring a handgun to anyone under 18, and the rule that raises the handgun age to 21 applies only to purchases from licensed dealers.2Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts Arizona imposes no additional state-level age restriction, so an 18-year-old can lawfully buy a handgun from a private seller.
Buyers under 18 need written consent from a parent or legal guardian, and selling or giving a firearm to a minor without that consent is a Class 6 felony in Arizona.3Arizona Legislature. Arizona Code 13-3109 – Sale or Gift of Firearm to Minor
Who Cannot Legally Buy a Firearm
Even with no background check in the way, federal law makes it a crime to receive a firearm if you fall into any of the following categories:4Bureau of Alcohol, Tobacco, Firearms and Explosives. Identify Prohibited Persons
- Anyone convicted of a crime punishable by more than one year in prison.
- Anyone under indictment for such a crime.
- Fugitives from justice.
- Anyone who unlawfully uses or is addicted to a controlled substance.
- Anyone a court has found mentally defective or who has been committed to a mental institution.
- Anyone in the country unlawfully, or, with limited exceptions, admitted on a nonimmigrant visa.
- Anyone discharged from the military under dishonorable conditions.
- Anyone who has renounced U.S. citizenship.
- Anyone subject to a qualifying domestic violence restraining order protecting an intimate partner or child.
- Anyone convicted of a misdemeanor crime of domestic violence.
Arizona separately defines “prohibited possessor” under state law, and the categories largely overlap with the federal list. If any of these apply to you, possessing the firearm is a federal crime regardless of how you got it.2Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts
The Seller Must Be an Arizona Resident
Arizona’s permissive private-sale rules apply only when both parties are Arizona residents. Federal law prohibits private individuals from selling firearms directly to someone who lives in another state, and any interstate transfer has to be routed through a licensed dealer in the buyer’s home state.5Congress.gov. Gun Control – Straw Purchase and Gun Trafficking Provisions in P.L. 117-159 – Section: GCA Interstate Transfer Prohibitions
This catches people off guard in border communities like Yuma and Lake Havasu City. If the seller’s ID shows a California or Nevada address, you cannot complete the purchase privately. You would need to find a licensed dealer in Arizona willing to receive the firearm and process the transfer, which brings the sale back under the usual federal paperwork and background check.
What to Bring and What to Ask For
Because no system is screening the transaction, you protect yourself by handling the basics in person. Bring a valid Arizona ID. Expect the seller to look at it, and ask to see theirs. You want to confirm the seller is an Arizona resident and that the person handing you the gun is the person named in any paperwork you create.
Inspect the firearm before money changes hands. Check that the serial number is intact and has not been scratched, filed, or otherwise altered. A suspiciously low price, a seller who won’t show ID, or a damaged serial number are signs to walk away. You can ask a local law enforcement agency to run the serial number to check whether the firearm has been reported stolen, though not all agencies will do this for private citizens. Knowingly possessing a stolen firearm is a Class 6 felony in Arizona.6Arizona Legislature. Arizona Code 13-1802 – Theft; Classification; Definitions
Writing a Bill of Sale
Arizona doesn’t require a written record of a private firearm sale, and a bill of sale carries no legal force on its own. It is still worth creating one. If the gun is later connected to a crime and the trail leads back through the previous owner, a dated record of the transfer can save you a great deal of trouble.
A useful bill of sale includes the date, the full names and addresses of both parties, driver’s license numbers, the firearm’s make, model, caliber, and serial number, the sale price, and a statement from you that you are legally eligible to possess firearms. Sign two copies and each keep one.
Running the Sale Through a Dealer Voluntarily
Either party can choose to route a private sale through a licensed dealer, and when you’re buying from someone you don’t know, it’s worth considering. It’s the only way to confirm through an official system that neither of you is prohibited, and it gives you a federal paper trail on the transfer. The process mirrors a regular dealer sale:7Bureau of Alcohol, Tobacco, Firearms and Explosives. Facilitating Private Sales – A Federal Firearms Licensee Guide you fill out ATF Form 4473, the dealer runs a NICS check, and if you clear, the dealer logs the firearm in from the seller and out to you.
Fees in Arizona typically run from about $25 to $75, and not every shop offers the service. Call ahead to confirm both the fee and whether the dealer handles private transfers.
Don’t Buy for Someone Else
If you are passing a background check or completing a private purchase on behalf of someone who can’t legally have the gun, or who simply wants to stay off any paper trail, that is a straw purchase. Federal law treats it as a serious crime carrying up to 15 years in prison, and up to 25 years if the firearm is intended for use in a felony, terrorism, or drug trafficking.8Office of the Law Revision Counsel. 18 USC 932 – Straw Purchasing of Firearms Buying a gun as a genuine gift is lawful; buying one because another person handed you cash and told you which gun to pick up is not.
