I don't see the upper on there either.  Been looking at the screen all day though so maybe I just missed it.  Does stripped barrel mean it isn't on the upper?  If that's the case you will also need a barrel wrench and it would really help to have an action block.  I have only built one myself though so don't go thinking I am an expert or anything.

I noticed the same thing.  It looks like you need a receiver extension, end plate, castle nut, buffer, and buffer spring.

Hand guard or float tube

Stock "guts"

Why not get the complete BCM upper receiver for $94?? Cheaper than al a carte and messin with the roll pin and C-clip are already done for you.

If you free float you don't need the barrel nut or delta ring.

Is the barrel a mid length or carbine? You might be buying the wrong gas tube. Roll pin for the gas tube.

Proper grease for the barrel threads.
