You cannot sell a gun on Facebook. Meta’s Community Standards prohibit private individuals from buying, selling, or trading firearms anywhere on the platform, and the same rule applies across Instagram, Messenger, and Meta’s ad network. Even if the platform allowed it, federal firearms law would still govern the transaction, and a casual online sale can carry federal criminal exposure.
What Meta’s Firearm Policy Bans
Meta’s restricted goods policy bars private sales of firearms outright. That covers the obvious listing in Facebook Marketplace, but it also reaches around the edges: arranging a sale through Messenger, posting in a group to find a buyer, or linking out to a website where someone can buy a gun from you privately are all prohibited.
The ban is broader than complete firearms. Meta also prohibits sales of:
- Ammunition
- Firearm parts and accessories, including silencers and suppressors
- Explosives and fireworks
- Non-powder guns, including paintball guns and BB guns
- 3D printing files for firearms and DIY gun kits, sometimes called “ghost guns”
Meta’s advertising rules mirror this. Ads promoting the sale or use of weapons, ammunition, or explosives are banned across Facebook, Instagram, and Messenger.
Licensed dealers get a narrow allowance. A firearms retailer or manufacturer can run a Facebook business page and promote the brand, but cannot accept orders or complete any part of a sale on the platform. Posting about a new product line is fine. “DM to buy” is not.
The Rules Apply Across Instagram and Messenger Too
Moving off Facebook to another Meta app does not create a loophole. Between April and June 2024, Meta took action on 242,000 pieces of firearm-related content on Instagram alone, not counting advertisements. A separate study of that same period found the majority of gun-related ads slipping through Meta’s filters appeared on Instagram rather than Facebook. Several people have been criminally charged in recent years for selling firearms and illegal gun accessories through Instagram profiles.
What Happens If You List a Gun Anyway
Meta uses a strike system that escalates with each violation. Automated detection and user reports flag posts, and confirmed violations get removed with a strike attached to the account.
- First strike: a warning.
- Two to six strikes: temporary restrictions on features like posting in groups.
- Seven strikes: a one-day ban on creating any content, including posts, comments, and new Pages.
- Eight strikes: a three-day content creation ban.
- Nine strikes: a seven-day content creation ban.
- Ten or more strikes: a 30-day content creation ban.
Firearm sales can fall under what Meta calls its “more severe policies,” which can add longer restrictions on top of the standard schedule. Continued violations lead to the account being disabled entirely.
The account is only part of the risk. People have been prosecuted specifically for selling guns through social media, and the fact that a post got removed does not undo whatever federal exposure the sale itself created.
Federal Law on Selling Guns Online
Whether a sale is legal has nothing to do with which website hosts the listing. Federal firearms law applies to every online gun sale, and two questions decide most of it: do you need a Federal Firearms License, and how does the transfer have to happen?
When You Need a Federal Firearms License
Anyone “engaged in the business” of dealing firearms must hold a Federal Firearms License (FFL) and run background checks on every buyer. The Bipartisan Safer Communities Act of 2022 expanded that definition. You are engaged in the business if you devote time and labor to dealing in firearms as a regular course of trade to “predominantly earn a profit” through repetitive buying and reselling. The older standard required proof someone was making a livelihood from gun sales. The current one catches sellers who are clearly in it for profit even if it isn’t their day job.
The Attorney General put it plainly when the rule was implemented: “It will not matter if guns are sold on the internet, at a gun show, or at a brick-and-mortar store: if you sell guns predominantly to earn a profit, you must be licensed, and you must conduct background checks.”
Dealing firearms without a required license is a federal felony. “I didn’t know I needed one” is not a defense that goes well in court.
Selling a Gun From Your Personal Collection
If you are genuinely selling a firearm from your own collection and not doing it as regular business activity, federal law does not require you to hold an FFL or run a background check. This is sometimes called the private sale exception. About 22 states have closed this gap by requiring background checks on all gun sales, including private ones, but federal law has not imposed a universal requirement.
Even a lawful private sale runs into interstate rules. If the buyer lives in another state, the firearm has to be shipped to an FFL in the buyer’s state, where the buyer picks it up after a background check and ATF Form 4473. Direct shipment to an out-of-state buyer without an FFL is not allowed. A narrow exception permits over-the-counter sales of rifles and shotguns to an out-of-state buyer when the transaction complies with the laws of both states. It does not cover handguns or unfinished frames and receivers.
Shipping the Firearm
How you can ship depends on the type of gun. Under 18 U.S.C. § 1715, handguns are nonmailable through the U.S. Postal Service, with exceptions only for shipments between licensed manufacturers and dealers and for certain government and law enforcement purposes. Mailing a handgun in violation of the statute is punishable by up to two years in prison.
Long guns can go through USPS. Private carriers like UPS and FedEx accept firearm shipments, including handguns, but impose their own requirements, which typically include overnight or two-day shipping for handguns and advance notice to the carrier. When the transfer crosses state lines, the package still has to go to an FFL on the receiving end.
Where Online Firearm Sales Actually Happen
Dedicated firearms marketplaces exist for legal gun sales. GunBroker runs as an auction-style marketplace. Armslist works more like classified ads, connecting local buyers and sellers. Guns.com combines retail with educational content, and several smaller platforms serve collectors and specific segments.
These sites do not exempt anyone from federal law. Interstate sales still ship to an FFL near the buyer, who runs the background check before releasing the firearm. Buyers typically pay the receiving FFL a transfer fee, commonly around $25 to $75 depending on the dealer, though some charge more. Many marketplaces publish directories of participating FFLs to make the handoff easier.
