Another milsurp wandered into my hands. The question is, is it worth the trouble to repair back to original shooting condition? Mum has been ground-off, front sight is bent, Bolt is missing firing pin, firing pin spring and safety/end cap. On the plus side: it does have Anti-Aircraft rear sight. It is my belief the stock is not cracked. It appears to be a factory splice. I would appreciate any thoughts? The rifle was passed on to me by a friend of a friend for me to clean and estimate repair cost. I have found a complete bolt for $130, not sure if individual parts are available. If its worth fixing, I may make her an offer. I would appreciate any thoughts or ideas.
