1) What markings should be on the barrel or receiver if it is indeed an ex-sniper? There are two holes in the left side of the receiver that have been filled in, and a piece of wood has been spliced to the stock to cover the original place for the scope mount. That is all I know. Are there certain markings that distinguish a sniper from the others by markings on the receiver or barrel?
2) How hard would it be to find an original / aftermarket scope and mount to fit the rifle? I do not want to remove the rear sight, and I would like it to be as close to original as possible.
Thanks in advance for all of your patience in answering the question.
