Honestly, once you looked at one and popped the pins to separate upper and lower, and withdrawn the bolt carrier from the upper, it's pretty clear.
The only thing to assemble is the small parts into the bare lower. That's a kitchen table job with simple tools. There are several very good online tutorials.
Most people just buy the upper already assembled and snap it onto the completed lower. Done.
If you have ever taken a lawnmower carb apart and reassembled it, you will have no problem with the lower.
