It is illegal to mail a handgun unless it goes FFL to FFL. It is legal to mail long-guns to yourself "in care of" someone else, but note that the someone else can neither open the box NOR "take possession" of the weapon. ATF has said before that means YOU have to BE THERE to receive the package.
Though I do not use them, my understanding is that neither UPS nor FedEx will let anyone ship a handgun to someone who is not an FFL holder.
I would talk to the FFL holder "in Tok" you want to ship "in care of," because if I were him I would refuse to participate because I would have no way to be sure it was not an illegal transfer. Anyone can write any name and address they want in the return-address area on the package.
