I found this online. I was particularly interested in number 6. Does anyone know if that is indeed correct? "Firearms shipping laws, in and of themselves, are surprisingly straightforward. According to Alcohol, Tobacco and Firearms, the bureau of the Treasury Department that regulates the nation's firearms trade, they boil down to this: 1) You can't mail handguns. You must send them via a private carrier, such as UPS or FedEx. 2) You can send long guns-- rifles and shotguns-- via the Postal Service or a private shipper. 3) You are required to tell the shipper that there's a gun in the package. 4) Neither you nor the shippers can label or mark the package in any way or fashion as containing a gun. 5) You can send and receive gun parts with no restrictions. As long as the parts don't add up to a complete gun (or a receiver, which in the eyes of the law is a complete gun), you can send and receive a barrel, a firing pin, grips or other components in any manner your preferences and pocketbook dictate. 6) You can send a gun to any resident of your own state, whether or not that person is a federal licensee (gun dealer, manufacturer, collector, gunsmith or importer). Outside your state, you can send the gun only to a licensee. The instate/out-of-state distinction is made, an ATF spokesman says, because: "The Treasury Department's authority in these matters is derived from the interstate commerce clause of the U.S. Constitution." If a gun doesn't move across a state line, it's not interstate commerce"
