My boss just bought a new WASR-10 that appears to have a major problem. When chambering a round the bolt will not go into full battery without forcing it forward the last half an inch. I switched out parts with my WASR-10 with the same results, and his parts worked fine in my gun. I sent it to a gunsmith who couldn't figure it out! It appears to have a fundamental flaw that is beyond me and the gunsmith to diagnose. What can be done with such a gun, other than to scrap it for parts?
