If I send a rifle or handgun back to a manufacturer for warranty work, when the firearm is repaired is it mailed directly to me? Or does it get shipped to a local FFL holder for transfer?
And what about the "from a friend" part? Not sure what your title means OP...
It depends on the State. In Louisiana and gun friendly states you're good. The others need to go through an FFL. The manufacturer will normally give a heads up.
