It's built on an RC from what I can tell. The matching bolt is humped - the number fonts don't match and the shelf looks melted. Real ones are either glass smooth or show swirled machine marks. The stock is heavily sanded to the point the recoil bolt is standing proud - you would have to count on the stock needing replacement. The rings and mounts are repro. Also, the SS markings on the rifle are FAKE. So is the death's head on the scope.
Basically, it is a total and complete fake made to deceive - regardless what the seller claims. Also, any joe-blo could reproduce that rifle for well under $3000.
