Kilibru;

I would recommend you do what I did when I had a dispute with the USPS local post office concerning a shotgun. I printed from the web the particular pages from the USPS Domestic Mail manual that described what firearms can be shipped by an individual who does not hold a FFL and futher printed the page that states that the post master does not have the authority to interpret the firearms regulations and laws. I carried this back to them and they were amazed and said "I had always thought we could not do that" as well as looked dumb.
