Step 2: Partially Disassemble the rifle.
Now, start to take your rifle apart. I was only doing a quick clean, so all I did was remove the bolt and scope. When doing a more elaborate check, take-down the whole rifle.
For the Mosin-Nagant taking out the bolt is simple. Just pull the bull to the rear, pull and hold back the trigger, and pull the bolt rearward out of the receiver. To take of the PU scope, I just unscrewed the bolt on the base and removed the mount and scope.
