On-line auction sites are like that. Lotta dealers who think they're going to get rich selling to new shooters/collectors on 'em.
I suspect that one has been refurbished/rebuilt/refinished.
E-Bay doesn't want you to be allowed to own any firearm. They actively fund the people who want to take 'em away from you. Last I heard they do not allow any firearms on their site. They have been known to confiscate, as in steal, funds from firearms related sellers too.
