Talked to the local post office today about mailing my buttstock and SB2 frame to Rem to have a barrel fitted. She was not able to say whether or not I can use the US Mail to ship the forementioned parts to the manufacturer. She said she would try to find out though. Simple question here- can I or not? I could of sworn that longarms were permissable to be mailed, you can't mail handguns and class 3 though.
