I just bought a used 10/22 and I have it "field stripped" but I would like to take apart the bolt and give it a good cleaning. The manual doesn't give any bolt disassembly instructions. The only thing I see is a roll pin that looks like it holds the firing pin in place. I was going to try and pound it out then go from there. If I do this, am I going to break anything or is there an easier way to go about it?
