You guys had me convinced, but apparently someone needs to explain the law to our post office personel. I called my local post office and was told that all firearms must go from FFL to FFL. I've read the ATF refulations, and they say that rifles and shotguns can be send by an unlicensed person to an FFL. I told her that it was only the action, and was about the size of your hand. She told me that it was concealable, and so it had to be sent via FFL to FFL. That being said, don't call the post office, they don't know the law as it applies to their services.
Thanks,
Michael
