I have to disagree with the sentiment that you just shouldn't take the bolt apart because it isn't easy. There are plenty of tricks to make it easier and less likely to end in tears.
Trick #1: Take it apart inside a plastic baggie. It is not much harder to disassemble with the bag around it and when things go flying, they only fly as far as the bag.
Trick #2: Buy a disassembly tool. M14Doctor has built an awesome one or for a little less you can get the USGI style that takes a little more figuring but works great.
Trick #3: Go to a clinic.
At some point you are going to want to disassemble that bolt. The extractor or ejector will break, some brass shavings will get stuck in the firing pin hole, the firing pin will wear down, etc. There are lots of reasons to disassemble to inspect, repair, or clean and it really isn't that hard with a little practice and/or the right tool.
