Picked up an sks today. Got it home, realized the internals had no cosmoline and were jampacked full of sand. The rifle itself is in great shape, no nicks. Every number matches on the gun. Bit confused on why there would be sand on the internals, but cosmoline covering the rest of the gun. Bore is in perfect shape as well. If anyone can chime in on why there might be sand in it, it would be great.
