I'm stuck on how a couple parts are suppose to line up. Swapping my USC fire controls over to my UMP NAVY lower.

Are there any diagrams on what goes where? I pulled a pin out too fact, some parts shot out and I'm sure how they went in or which direction some of the springs go.

I can't find my USC manual to check for a diagram. Anyone got an armors manual in PDF or a link to a guide?
