How to Legally Sell a Firearm You Own
At some point a lot of owners decide to move a firearm along. Maybe you upgraded, maybe a gun no longer fits how you shoot, or maybe you inherited something you have no use for. Selling it is completely legal, but the way you go about it matters more than people expect. Federal law sets a floor that applies everywhere, your state stacks rules on top, and a careless sale can turn an ordinary transaction into a serious problem. Here is how to do it the right way, with the least risk to you.
Know who you are allowed to sell to
The single most important rule in any private sale is this: you cannot sell or give a firearm to someone you know or have reason to believe is prohibited from owning one. Federal law lists categories of people who cannot legally possess firearms, including convicted felons, people under certain restraining orders, and others. If you hand a gun to someone in one of those categories, you can be on the hook even if the sale felt casual and friendly.
That is why the safest private sales are never blind. You want to sell to someone you can reasonably confirm is a legal, eligible adult, and you want to avoid anyone who raises a red flag. If a buyer is cagey about showing ID, wants to rush, offers to overpay to skip steps, or says anything that hints they cannot buy from a dealer, walk away. A bad feeling is a good enough reason to stop. The goal is not just to follow the letter of the law but to keep yourself out of a situation you cannot prove you handled correctly.
When the sale has to go through a dealer
Federal law treats an in-state, private, one-time sale between two residents of the same state differently from a sale that crosses state lines. The line that trips people up most is residency.
If you are selling to someone who lives in a different state, federal law generally requires that the firearm go through a licensed dealer, normally one in the buyer’s state, who runs the background check and handles the transfer. You cannot simply meet a buyer from another state in a parking lot and hand the gun over. That restriction is not limited to handguns. As a private seller you may not transfer a firearm of any kind directly to a resident of another state, rifles and shotguns included. It applies even between private individuals with no business involved. The interstate piece is what pulls a dealer into the picture, and it works much like buying a gun online: the firearm ships to an FFL near the buyer, who completes the paperwork. The article on how FFL transfers work walks through that process from the receiving end, and buying a firearm online covers the same flow from the buyer’s side.
Within your own state, federal law may permit a direct private sale between residents, but this is exactly where state law takes over and varies enormously. Some states require every transfer, including private ones, to run through a licensed dealer with a background check. Others require the buyer to hold a permit or license. Others allow a simple face-to-face sale between residents. Because the rules are so different from place to place, you have to confirm what your state requires before you sell. Do not assume the federal floor is the whole story.
If you are not sure where your state lands, ask a licensed dealer before you agree to a sale rather than after. B&S Defense can explain how a private-party transfer works and handle the dealer side of one by appointment.
Run it through an FFL even when you are not required to
Here is a practical point that goes beyond the bare legal minimum. Even when your state would let you sell directly to another resident, running the sale through a licensed dealer is often the smarter move. A dealer runs the background check, documents the transfer, and gives both sides a clean record that the buyer was eligible at the time of sale.
That paper trail protects you. If a firearm you once owned later turns up somewhere it should not, a documented transfer through a dealer shows exactly when it left your hands and that the buyer passed a check. A handshake sale gives you none of that. For many sellers, the modest transfer fee is cheap insurance against a future headache. A shop can handle this kind of transfer by appointment, and the cost is in line with any standard transfer.
Keep your own records either way
Whether or not a dealer is involved, keep a record of the sale for yourself. At minimum, note the date, the make, model, caliber, and serial number of the firearm, and how the transfer was handled. If the sale went through a dealer, keep your copy of any receipt or paperwork they give you.
Recording the serial number matters most. It is the number that ties a specific firearm to a specific transaction, and it is what you would point to if you ever needed to show that a gun was no longer yours as of a certain date. If you are not sure where to find it, it is stamped on the serialized part of the firearm, which on many guns is the frame or receiver. The article on whether a lower receiver needs an FFL explains why that serialized part is the piece the law actually tracks.
Sales that carry extra rules
A few situations come with their own wrinkles, and it is worth knowing where they are.
- Selling a gun that falls under the National Firearms Act, such as a suppressor or a short-barreled rifle, follows a completely separate transfer process with its own federal paperwork and approval. You cannot move those items like an ordinary firearm. The article on the National Firearms Act explains what is covered and why those transfers work differently.
- Inherited firearms get a narrow break. Federal law carves out an exception for a firearm passed by bequest or intestate succession, so an inheritance can cross state lines without going through a dealer, provided you can lawfully possess it where you live. That exception covers the inheritance only. The moment you decide to sell the gun, the ordinary rules come back: you need an eligible buyer, and an out-of-state buyer still means a dealer in the middle.
- Selling repeatedly for profit can cross the line into “dealing” in firearms, which requires a license. The statute is explicit that this does not cover a person who makes occasional sales to enhance a personal collection or as a hobby, or who sells all or part of a personal collection, so thinning out your safe is not dealing. What counts as crossing the line is the unsettled part. Congress broadened the statutory definition in 2022, and the federal regulation written to spell out what that means has since been through litigation and is being rewritten, so the practical boundary is in flux. If you are buying and reselling with any regularity, get advice before you continue rather than guessing.
Avoid the one mistake that creates real trouble
The transaction to stay far away from is a straw purchase, where someone buys or sells a gun as a stand-in for a person who cannot legally have one, or who wants to hide that they are the real buyer. That is a federal crime, and it is treated seriously. If a buyer asks you to sell to them so they can pass the gun to someone else, that is a hard stop. The article on what a straw purchase is explains how these deals get people charged and why even a favor for a friend can become a felony.
Selling a firearm you own is routine and legal when you do it with a little care. Confirm your buyer is eligible, respect the line between an in-state private sale and an interstate one, lean on a licensed dealer when it adds protection, and keep your own record. Do that, and a sale stays exactly what it should be: simple.
Firearm sale and transfer laws vary widely by state and town, and some states require all transfers, including private sales, to go through a licensed dealer or require the buyer to hold a permit. Nothing here tells you what your own state requires, so confirm the rules that apply where you live before you sell. The federal points described here reflect law as of July 2026 and are subject to change through legislation, regulation, and court decisions, and the federal standard for when repeat selling becomes unlicensed dealing is unsettled at the regulatory level. This article is general information, not legal advice. If a specific sale leaves you unsure, ask a licensed dealer or an attorney before you go through with it.
Frequently asked questions
Can I sell a gun to a friend or family member? Within your own state this may be allowed under federal law, but it depends entirely on your state’s rules, which range from a simple face-to-face sale to a required dealer transfer or permit. Confirm what your state requires first, and never sell to anyone you believe cannot legally own a firearm.
Do I have to do a background check on a private sale? Federal law does not require a private seller to run a check on an in-state sale, but many states do require one, usually by routing the sale through a licensed dealer. Even where it is optional, running the check through a dealer protects you with a documented record.
Can I sell my gun to someone in another state? Not directly. A sale to an out-of-state buyer generally has to go through a licensed dealer in the buyer’s state, who runs the background check and completes the transfer, the same way an online purchase ships to a local dealer.
Should I keep a bill of sale? Yes. Record the date, the firearm’s make, model, caliber, and serial number, and how the transfer was handled. That record shows when the gun left your possession and is worth keeping indefinitely.
What if the buyer seems suspicious? Stop the sale. You are not required to sell to anyone, and you can be held responsible for transferring a firearm to a prohibited person. If anything feels off, walk away.
