How to Sell a Gun Legally

Selling a firearm in the United States is governed by both federal and state law. Federal law sets nationwide standards, but your state decides how private sales, background checks, paperwork and dealer transfers actually work.

Federal age update (as of Oct 2026): On Sep 17, 2026 the U.S. Department of Justice said it will not criminally enforce the federal 21+ age limit on licensed-dealer handgun sales to law-abiding 18–20-year-olds. The federal statute (18 U.S.C. § 922(b)(1)) is unchanged, and state age limits still apply. DOJ announcement

Step-by-step

How to sell a gun legally: the steps

  1. 1

    Choose a private sale or an FFL transfer

    Some states allow private sales between residents; others require the transfer to go through a federally licensed dealer (FFL). Check your state guide below before you agree to a sale.

  2. 2

    Confirm the buyer is eligible and handle the background check

    Federal law prohibits transferring a firearm to a prohibited person (18 U.S.C. § 922). Dealer transfers include a background check; whether a private sale needs one depends on your state.

  3. 3

    Complete the paperwork and a bill of sale

    Paperwork, permit and registration rules vary by state. Even where it is not required, a written bill of sale with the date, firearm make, model and serial, and buyer details is a sensible record.

  4. 4

    Ship or sell across state lines only through an FFL

    Private interstate firearm transfers are prohibited under federal law. If the buyer lives in another state, the transfer must go through licensed dealers.

Federal firearm laws are primarily enforced under 18 U.S.C. § 922 and administered by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). See the ATF guidance on prohibited persons and our federal and state law overview.

How to sell a gun legally in your state

Every state has its own approach. Some allow private sales without additional requirements, while others mandate background checks, waiting periods, registration or transfer through a licensed dealer. Select your state for its step-by-step guide.

These guides cover compliance only and are not legal advice. If you would rather skip the private sale, you can sell directly to We Buy Guns, a federally licensed dealer.
