Let's say my brother has his hands on a great deal for a very rare deer rifle. He is an Oregonian with an active Driver's license and votes in Oregon. But he lives in Texas - at Fort Hood on Active Duty with the U.S. Army. Because of this he can buy guns in Texas - long guns and pistols and all - under federal law. He buys the rifle and the next time he sees the family in Oregon, he gifts the rifle to one of his brothers. Any problems or issues with that transfer??
