Ahhhh- what do they call those adult diapers???? Oh yeah- DEPENDS.
Depends on your STATE laws- and I don't know what state you are in.
FEDERAL law permits a face to face sale between 2 unlicensed residents of the same state ONLY. Unlicensed means does not hold a FFL. So if you lived in, say, Virginia, you could sell a rifle, shotgun, or pistol to another resident of VA- so long as you did not have cause to believe they were prohibited from owning a gun. But the guy that wants to drive down from Maryland? Nope. You CAN transfer it to a dealer, who could then transfer it to him, or to a FFL in his home state.
