The problem with what you are asking is that most "how to" sites deal with aegs or gas guns. You have a spring rifle without a standard mech box. It's almost next to impossible to link you to a guide for something like that. Every brand of springers I've ever used happened to have a different build regaurdless of the gun type (m4 etc). Hate to say it but you might be on your own with this one. Pictures might help but that's all I can suggest.
