It is a standard upgrade personal project gun. Judge it by the quality of work. It is not a factory original and can not be valued like one. If a buyer wanted a factory high grade gun he has to be willing to pay the price. Only a seller expects a buyer to pay the same money for a upgraded gun.

If you cam across a "upgraded" painting of Mona Lisa done by someone who wanted the Mona Lisa but could not buy the original would you pay the same money for the upgrade? No, even if it was a perfect copy. Same thing for upgraded guns that mimic a high grade or rare gun. Looks the same is not the same and the money should not be there.
