I recently purchased a complete upper assembly including the barrel, barrel extension, toggle, breechblock, firing pin assembly and including all the other miscellaneous parts needed to slide on the frame and fire. This was shipped to me USPS Priority I assume as parts. As I think we all know you cannot ship a handgun or firearm that can be concealed though the mail. It must be declared as a firearm and shipped overnight either FEDEX or UPS. According to the USPS website and in speaking with FEDEX today the complete upper assembly of a Luger is a firearm and not considered parts even though it is not the serialized frame. The barrel extension itself meets all the requirements of a receiver. Some of you may already know this so I will leave the post as is for now. I will fill in the details if need be....your thoughts.
