Short Answer: To legally sell a gun, FFL dealers must conduct a background check on the prospective buyer, complete ATF Form 4473 accurately, and record the firearm transaction in an A&D record (bound book). Private sellers must follow state law requirements, which vary by location.

Federal Laws Governing Firearm Sales in the United States
Federal law forms the foundation of all firearm transactions in the United States. The Gun Control Act requires that anyone engaged in the business of selling firearms must hold a Federal Firearms License (FFL). This applies to gun shops, pawn shops, and any dealer conducting regular firearm sales.
The National Instant Criminal Background Check System (NICS) is the primary tool for screening prospective purchasers. When a potential buyer wants to purchase a firearm, the licensed dealer submits their information to NICS or the state background check system. This verifies the buyer is not a prohibited person under federal law.
Regulations for Different Firearm Types
Different categories of firearms have specific legal requirements:
- Handguns: Buyers must be at least 21 years old when purchasing from a licensed gun dealer
- Long guns (rifles and shotguns): Buyers must be at least 18 years old for purchases from licensed dealers
- NFA items (short-barreled rifles, machine guns, fully automatic firearms, silencers): require ATF approval, a background check, and fingerprinting
State and Local Firearm Sale Requirements
While federal law provides baseline standards, state law can add significant requirements. Some states mandate universal background checks for all gun sales, including private transactions. Others require waiting periods, permits, or registration.
Selling a firearm across state lines involves additional restrictions. Federal law prohibits direct sales of handguns to residents of another state. These transfers must go through a licensed firearm dealer in the buyer’s home state.
Firearm laws change frequently. Always check current regulations through the ATF website and your state’s law enforcement resources before completing any gun sale.
Steps to Legally Sell a Gun as an FFL Dealer
1. Obtain Your Federal Firearms License
Before you can legally sell firearms as a business, you must obtain an FFL through the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF). The application process includes a background check, interview, and inspection of your business premises.
2. Prepare the Firearm for Sale
Verify the firearm is legal to sell in your state and the buyer’s state. Check that the serial number is visible and matches your A&D records. Confirm the firearm is not stolen by checking with law enforcement databases when required.
3. Verify the Buyer’s Eligibility
Conduct a required background check through NICS or your state’s system. The prospective buyer must provide valid identification and answer questions on Form 4473 to confirm they are not a prohibited person. Prohibited categories include felons, domestic violence offenders, unlawful drug users, and individuals adjudicated as mentally defective.
4. Complete ATF Form 4473
The buyer must complete ATF Form 4473, providing their name, date of birth, identification details, and answers to eligibility questions. You must verify this information matches their ID and record all firearm details, including make, model, and serial number.
5. Maintain Accurate A&D Records
Record every firearm transaction in your Acquisition and Disposition (A&D) record, also called a bound book. This includes the firearm’s details, the buyer’s information, and the transaction date. These records must be available for ATF inspection and kept for at least 20 years.
How Licensed Firearm Dealers Handle Gun Sales
Federal firearms licensees play a central role in preventing firearms from reaching unlicensed persons who should not have them. FFL dealers serve as the checkpoint between manufacturers, distributors, and the public.
Benefits of Working with a Licensed Dealer
- Access to NICS for conducting background checks
- Proper handling of ATF Form 4473 and required paperwork
- Organized records available for law enforcement audits
- Legal protection through proper documentation
Pawn Shop and Gun Shop Requirements
Pawn shops and gun shops that buy, sell, or trade firearms must hold a Type 1 or Type 2 FFL. If your pawn shop does not deal in firearms, no FFL is required. FFL dealers must notify law enforcement if they unknowingly accept a firearm from a prohibited person.
Private Sale Requirements for Gun Owners
A private sale occurs when an individual who is not a licensed dealer sells a firearm to another individual. Federal law does not require private sellers to conduct background checks in most cases. However, it is illegal for any person to sell a firearm to someone they know or reasonably believe is a prohibited person.
State Background Check Requirements for Private Sales
Many states now require universal background checks for all firearm transfers, including private transactions. In these states, the private seller must complete the sale through a licensed gun dealer who runs the background check. Check your state law before completing any private firearm sale.
Transferring Firearms to Family Members
Some states allow firearm transfers between immediate family members without a background check. This typically includes parents, children, spouses, and siblings. Even in these cases, transferring a firearm to a family member who is a prohibited person remains illegal under federal law.
Avoiding a Straw Purchase
A straw purchase occurs when someone buys a firearm on behalf of another person who cannot legally purchase it themselves. This is a federal crime with serious penalties. Always verify that the actual buyer is completing the transaction and Form 4473.

It depends on your state. Some states exempt immediate family member transfers from background check requirements. However, you cannot transfer a firearm to any family member who is a prohibited person under federal law.
If you are engaged in the business of selling firearms, you need an FFL regardless of location. Occasional sales from a personal collection may not require a license, but regular sales for profit do.
Handgun sales across state lines must go through an FFL dealer in the buyer’s state. Long gun sales may be completed in person if legal in both states, but many sellers use a licensed dealer for interstate firearm transfers.
Knowingly selling a firearm to a prohibited person is a federal crime. Even unknowing sales can lead to legal consequences if you had reasonable cause to believe the buyer was prohibited. Background checks and documentation protect sellers.
