I would add that I have been a various gun shows, where 1 party was buying a weapon for another party. Both people were at the show, but one party had moved and told the seller that the address on the DL did not match where they actually lived.
So the other party, who's DL matched their house, offered to buy it for the other person. The seller would not allow it, knowing it was for someone else and not the person actually filling out the 4473.

I state this, not to say what is legal or not, but just be careful when you are buying it, you don't tell the wrong person that "I am buying this for this or that person", it may save you confusion, regardless that the law says that it is LEGAL to do so.
