I started this question day's ago and just now came back in. Let us say man is doing gunstock refinishing or rechequering of lazer cut factory stoks. He is not your brother inlaw. He does this work for money. he lives in another state. It is not the loan of firearm in normal sense of the word.Reading all the replies here I conclude he must have a Ffl for gunsmithing type of work otherwsie the customer and man doing the work are in violation of the law .Correct?
