I second Troy. Mark it as a gun, otherwise you will be sucking air if it gets stolen and you want to collect on the insurrance. Here is a quote from Fed Ex:
Firearms. FedEx will only accept shipments of firearms when either the shipper or recipient is a licensed manufacturer, licensed importer, licensed dealer or licensed collector and is not prohibited from making such shipments by federal, state or local regulations when these conditions are met. FedEx will accept and deliver firearms between all areas served in the U.S. and Puerto Rico.
Firearms must be shipped via FedEx Priority Overnight and may not be sent C.O.D. Upon presenting the package for shipment, the shipper is required to inform FedEx that the package contains a firearm. Firearms may not be shipped in one complete piece. When tendered for shipment, the firearm must be rendered inoperable, either by removing the firing pin in the gun and disconnecting the barrel, or by some other means so the package does not contain a completely assembled, usable weapon. The outside of the package should bear no label, marking, or other written notice that a firearm is contained within. This includes the abbreviation of the name of the shipper or recipient if the name would clearly indicate that the package could contain a firearm. Firearms and ammunition may not be shipped in the same package. Ammunition is always an explosive and must be shipped as Dangerous Goods. Signature release is not available for shipments containing firearms.
The shipper and recipient are required to comply with all applicable government regulations and laws including those pertaining to labeling. The local division office of the Bureau of Alcohol, Tobacco and Firearms (ATF) can provide assistance with the packaging and shipment of firearms.
