I don't know how he is moving, whether it be by plane or not, but i'd suggest just driving to the location, with your guns in the vehicle. Guns in the trunk, unloaded, with ammo separate. If you get pulled over, this'll save you if they are all gun locked and 'squeaky safe'. However if you are the one moving the firearms, you'll have to consider them yours for the time being. Most cops aren't gonna be too convinced of "I'm moving these for a friend".
Otherwise, just find a local FFL who's nice and respectable, and have them shipped to a FFL in the area he/you is moving to so you can pick them up there.
As edwardware points out, show up to a FFL with a gun, it's yours. Your friend should be the one doing this. If you do this, then they're 'yours' for the time being.
