He can ship the gun directly back to you as you are still the owner. You can ship a firearm to Ruger for repair and they can ship it back to you. You are the owner of the gun. He did record the gun in his bound book but its the same as if you lived in his state and brought the gun in to be fixed and picked it up next week. As long as you picked it back up, there is no paperwork as you retained ownership of the gun. What state did you ship to? Good luck,
