ya you have to make sure that thing hasn't been stolen or used in a crime, my cousin bought a gun privately he got pulled over and the cop ran the number the gun was stolen. My cousin almost went to jail, turned out the guy he bought the gun from had a pretty good collection of stolen items in his house.
Better to be safe then sorry
