I can tell you one thing I DO remember clearly from taking the bolt apart. Keep the chamber end of the bolt pointed AWAY from you at all times.
At one point in the disassembly the bolt jumped in my hand and when I looked to see what had happened the entire striker assembly was sticking out of the wall like a spear. It embedded a good 2 inches into the wall. I was very happy that it wasn't pointed at me when it let go.
