What is an FFL and why do I need one?
An explanation of Federal Firearms Licenses and why every GatSwap transfer uses one.
A Federal Firearms License (FFL) is a license issued by the ATF that authorizes a business to engage in the manufacture, import, or dealing of firearms. When you buy or trade a firearm through GatSwap, the physical transfer always happens at an FFL — never directly between two private parties by mail.
Why is an FFL required?
Federal law (18 U.S.C. § 922(a)) prohibits interstate transfers of firearms between unlicensed individuals. By routing every trade through a licensed FFL, GatSwap ensures every transfer is legal, documented, and includes a NICS background check.
What does the FFL do?
- Receives the firearm from the seller's FFL via licensed carrier
- Verifies the buyer's identity against their government ID
- Has the buyer complete ATF Form 4473
- Runs the NICS background check
- Releases the firearm to the buyer once cleared
All FFLs in the GatSwap network are license-verified and community-rated. You can view an FFL's rating and reviews before selecting them for your transfer.
