It's quite a bit easier to understand when you have everything in your hands.

I don't have a link for you, but there was a two part video I watched on YouTube that demonstrated the complete disassembly of a WE G39. Search for that, and the job of disassembling the bolt will be much easier.

Alright thanks for both of your input.
