My guess is that they will never allow someone like
Joe Maddalena or the prop store guys to take a Close look.
Actually well before this Pawn Stars episode came out they DID take it to the Prop Store... which was when I learned about it. At that time I saw all the images of this thing in high res, which was when I determined that it was fake aside from the scope and MAYBE the top scope rings of the mount. I passed that opinion on to TPS and then, my guess is after being rejected by the Prop Store they went to Pawn Stars to try their luck.
I'm fairly convinced the scope is legit. Up close it's got way too much detail to be faked that perfectly in my honest opinion.
