I'm sure the T-tracks and rods, as well as the 3 piece front grill assembly all being plastic pieces glued on, have all fallen off by now. It does seem to have a real scope or at least a good replica because one screen grab does show a number on it, looks like "9761." The flash-hider looks odd, sort of like a old coin that was improperly cleaned. Where is the patina? The only shot showing the rear of the gun does have some stamped numbers - so it may be a real Mauser here.
