I just took shipment of my chinese sks last week. On closer inspection, it has light pitting all over the place some scrubbed some not. Is this normal for chinese sks's? Its a factory 106 all matching#. I don't know if it was in combat but why would a soldier in a time of peace let his gun rust? More to the point why was he allowed to let it rust(most officers are kind of sticklers on that point I would think). I don't really care about it(its a well made milsurp example) just curious Any ideas?
