FIREARM TRANSFERS
- Firearms must ship to a licensed FFL dealer of your choosing — confirm with them first that they can accept the transfer.
- Your receiving FFL will need to email their license to [email protected] before we can ship.
- Inspect your firearm at your FFL’s location before signing ATF Form 4473 — once signed, the firearm is considered accepted.
You’re responsible for knowing the firearms laws in your state before ordering. For complete shipping, returns, and restocking-fee policy details, see our Shipping & Returns page.
