i don't know if this is the case but have had a like sale happen once. Seller sold me a firearm at a very good price, later told me it was stolen and tried to get it back by giving my money back. Just didn't seem right, so I had a buddy who is on the police force run the number, gun wasn't stolen, seller found out the gun was worth about twice what he sold it to me for and was just trying to renege on the sale.
