Perhaps whoever took it apart discovered the rifle was not performing properly and decided to try and 'fix' it. I cannot think of anything in that region which could easily be broken since the rifle is very robustly constructed but, however, he may have lost a part or parts. I think you need to be wary and if possible try and examine it more closely and then make a decision.
