Well I'm no lawyer or cop but I say that if you hypothetically came across something like that and you didn't buy it out of a Chevy caprise's trunk in a dark alley on the not so nice part of town then I say it was a gift and hide it very very well. Hypothetically of course. It would not be my primary HD gun and I would not keep it in my safe. I would part it out and maybe keep it for SHTF. But that is a personal choice I would be very very careful with your hypothetical situations.
