Private Firearm Sales in Arizona: What Every Buyer and Seller Needs to Know

Somebody in your neighborhood group chat is selling a Glock 19 for cash, no paperwork, no questions asked. Is that even legal in Arizona? Short answer: yes, mostly. But “mostly legal” is exactly the kind of phrase that gets people into trouble, so let’s get specific about private firearms sales in Arizona and what the law actually says, not what your cousin at Thanksgiving told you.

Arizona is one of the more hands-off states in the country when it comes to gun ownership. That freedom is exactly why private citizens need to know the boundaries. Fewer state rules doesn’t mean zero rules. Federal law is still very much in play, and a mistake here isn’t a slap on the wrist. It can be a felony.

Is It Legal to Sell a Gun Privately in Arizona?

Yes. Arizona allows private party firearm sales between two residents of the state without going through a licensed dealer. There’s no state-mandated background check, no waiting period, and no registration requirement for the transaction. This applies whether you’re selling a bolt-action deer rifle you inherited from your grandfather or a handgun you picked up at a gun show and decided you don’t love.

That said, “private” means private individual to private individual, not a side hustle. If you’re regularly buying and reselling firearms for profit, federal law may consider you to be “engaged in the business,” which requires a Federal Firearms License (FFL). Selling a few guns from your own collection over the years is fine. Flipping ten guns a month off Facebook Marketplace is a different story, and the ATF has prosecuted people for exactly that.

Arizona’s Background Check Rules for Private Sales

Arizona Revised Statutes do not require a background check for private firearm transfers. This puts Arizona in the same camp as most of the Mountain West and stands in contrast to states like California or New York, which require every sale, private or otherwise, to run through a licensed dealer for a NICS check.

If you want a background check anyway, for your own peace of mind or the buyer’s, you can request one through a local FFL. Many gun shops and ranges will run a check for a small transfer fee even when it’s not legally required. It’s a smart move if you’re selling to someone you don’t know well. Our FFL transfer service exists for exactly this situation.

Federal Law Still Applies, Even Without a State Check

Here’s where people get tripped up. Just because Arizona doesn’t require a background check doesn’t mean federal law disappears. Under 18 U.S.C. § 922(d), it is a federal crime to sell or give a firearm to someone you know or have reasonable cause to believe is a prohibited person. “I didn’t run a check” is not a legal defense if there were obvious red flags, like the buyer telling you outright they just got out of prison.

The takeaway: no background check requirement doesn’t mean no responsibility. Sellers are still expected to use reasonable judgment.

Who Can’t Legally Buy or Own a Firearm

Regardless of how the sale happens, federal law prohibits certain people from possessing firearms. This includes:

• Convicted felons (with very limited exceptions for restored rights)
• Anyone under a domestic violence restraining order that meets federal criteria
• People convicted of misdemeanor domestic violence
• Individuals adjudicated as mentally defective or involuntarily committed
• Unlawful users of controlled substances
• Undocumented immigrants and certain visa holders
• Dishonorably discharged veterans

Selling to any of these individuals, even privately and even without a background check, is a federal crime known as a straw purchase or unlawful transfer, and it carries real prison time. If something about a buyer feels off, trust that instinct.

Age Requirements for Private Firearm Transactions

Federal law sets the baseline: licensed dealers can’t sell handguns to anyone under 21 or long guns to anyone under 18. Those age limits technically apply to FFLs, not private sellers, which creates a gray area for person-to-person sales.

Arizona doesn’t add a separate state law explicitly setting a minimum age for private handgun sales, but it does make it illegal for a minor to possess a firearm without the consent of a parent or guardian under most circumstances (ARS 13-3111). In practice, most private sellers stick to the same 18-for-long-guns, 21-for-handguns standard that dealers use. It’s the safer, more defensible line to hold, even if the letter of the law is murkier.

Selling Across State Lines

This one trips up a lot of people who meet buyers online. If you’re selling a firearm to someone who lives outside Arizona, you generally cannot hand it directly to them, even if you meet up in person somewhere in Arizona. Federal law requires that interstate private transfers of firearms go through an FFL in the buyer’s home state. The seller ships the firearm to that dealer, who then runs the required background check and completes the transfer according to that state’s laws.

There’s no shortcut here. Meeting an Arizona buyer’s “cousin from Texas” in a parking lot in Flagstaff and handing over a pistol is a federal violation, regardless of how casual it feels. If you regularly sell to out-of-state buyers, our consignment and transfer desk can walk you through the process correctly.

Do You Need a Bill of Sale?

Arizona law doesn’t require one for a private firearm sale. But skipping it is a mistake plenty of people regret. A simple bill of sale protects both parties. If that gun is ever used in a crime after you sold it, a signed document with the date, both parties’ names, ID information, and the firearm’s make, model, and serial number is your evidence that you’re not the last legal owner.

At minimum, write down:

• Date of sale
• Full names and addresses of buyer and seller
• Firearm make, model, caliber, and serial number
• Sale price
• Signatures of both parties

Keep a copy. It costs nothing and takes two minutes, but it’s the difference between a quick phone call to police and a genuinely stressful investigation if that firearm turns up somewhere bad down the road.

Arizona’s Constitutional Carry Law and What It Means for New Owners

Since 2010, Arizona has allowed constitutional carry, meaning anyone 21 or older who can legally possess a firearm can carry it concealed without a permit. You can still apply for a Concealed Weapons Permit voluntarily, and it’s worth doing if you plan to carry in other states that honor Arizona’s permit through reciprocity agreements.

If you just bought a used handgun through a private sale, understand that legal ownership and lawful carry are two separate questions. You still need to know where carry is restricted, including K-12 schools, polling places on election day, and posted establishments that serve alcohol for on-site consumption. New owners who want hands-on guidance often benefit from a concealed carry safety course before they start carrying regularly, permit or not.

Special Rules for NFA Items and Machine Guns

Not everything sold privately follows the simple handshake-and-cash model. Items regulated under the National Firearms Act, suppressors, short-barreled rifles, and pre-1986 fully automatic weapons, require ATF approval for any transfer, private or otherwise. That means Form 4 paperwork, a tax stamp, and a waiting period measured in months, not minutes. Skipping this step isn’t a minor paperwork issue; it’s a federal felony involving unregistered NFA items.

Local Ordinances Don’t Apply — Thanks to State Preemption

Some states let cities pass their own gun ordinances on top of state law. Arizona isn’t one of them. Under ARS 13-3108, the state preempts local governments from regulating the sale, transfer, or possession of firearms beyond what state law already covers. So a Tucson city ordinance can’t add a background check requirement that Phoenix or the state doesn’t already have. This keeps the rules consistent no matter where in Arizona the sale happens, which is honestly one of the simpler parts of all this.

Smart Practices for Private Sellers (Even When Not Required by Law)

Just because the law sets a low bar doesn’t mean you have to stop there. Sellers who want to protect themselves and act responsibly tend to:

• Ask to see a valid government-issued ID and cross-check it against the buyer’s name on the bill of sale
• Meet in a public, well-lit location, ideally one with security cameras
• Consider a voluntary background check through a local FFL for higher-value firearms
• Trust their gut. If a buyer seems evasive, nervous about ID, or insists on cash-only with no paper trail, walk away
• Photograph the firearm and serial number before the sale for their own records

None of these steps are legally mandatory. All of them are common sense, and they’re the same habits responsible gun owners have followed for decades, long before anyone was buying and selling through phone apps.

Key Takeaways

• Arizona does not require background checks, permits, or registration for private firearm sales between residents.
• Federal law still prohibits knowingly selling to felons, domestic abusers, and other prohibited persons, regardless of state rules.
• Most private sellers follow 18+ for long guns and 21+ for handguns, even though Arizona law doesn’t explicitly spell this out for private transactions.
• Interstate private sales must go through an FFL in the buyer’s home state; you cannot hand a gun directly to an out-of-state buyer.
• A written bill of sale isn’t required but is one of the smartest, cheapest protections a private seller can use.
• NFA items like suppressors and machine guns require ATF-approved transfers no matter who’s selling them.
• Arizona’s state preemption law means local cities can’t add their own extra firearm sale requirements.

Frequently Asked Questions About Private Firearm Sales in Arizona

Do I need a background check to sell my gun privately in Arizona?

No, Arizona doesn’t require a background check for private, in-state firearm sales. You can still request one voluntarily through a local FFL if you want extra peace of mind, especially when selling to someone you don’t know.

Can I sell a firearm to someone who lives in another state?

Not directly. Federal law requires that the firearm be shipped to a licensed dealer in the buyer’s home state, who will then run the background check and complete the transfer according to that state’s laws.

Is a bill of sale required for a private gun sale in Arizona?

It’s not legally required, but it’s strongly recommended. A signed bill of sale with both parties’ information and the firearm’s serial number protects you if that gun is ever connected to a crime after the sale.

Can I carry a gun I just bought privately without a permit?

If you’re 21 or older and legally allowed to own a firearm, Arizona’s constitutional carry law lets you carry concealed without a permit. You’ll still need to know where carry is restricted, such as schools and certain posted businesses.

What happens if I unknowingly sell to a prohibited person?

Federal law focuses on what you knew or reasonably should have known. If there were clear warning signs and you ignored them, you could face federal charges even without a background check requirement. Using common sense, checking ID, and trusting your instincts goes a long way toward staying on the right side of the law.
