Can I mail a firearm?

YES. . . and NO.  You can also personally ship rifles or shotguns via the USPS, UPS, and FedEx to a dealer in another state. As a non-FFL, you can only ship handguns FedEx or UPS, and they want you to send it Overnight. Your dealer can ship anything for you for a small fee and many times can save you time and money in the process.
