A friend of mine recently received a firearm as a gift from a mutual friend of ours. However, they did no type of transfer of any sort. I told them that wasn't a good idea and that they should transfer it through a FFL deal for legality reasons. The issue is that we in the military and they both have different states of residence, and to make the issue harder one of them executed orders to a different state. What is the best course of action to avoid any type of legal blowback. Can anyone provide some insight on advice I can pass on? Thank you.
