An F-I-L is not classed as a parent in this case. Yes, he could gift it to his daughter (parent-child) and she could gift it to him (spouse-spouse).....As long as both can legally own a gun. If wife had something that prohibited her from owning, her dad could not give it to her; and if hubby had something that did not allow him to own, then she could not give it to him.
