A-a 1952 30-30 is not a primitive firearm. B- you don't need to use a FFL when shipping a long gun within the State. (If that was the case) C- This does raise an interesting question. Is one breaking the law, bringing a firearm into the post office to be shipped?Kinda off track, but if you can ship a primitive firearm (I shipped a 1952 era 30-30) to an FFL holder through the post office, how's that figure in?
