I see the instructions on how to swap barrels. I see the Diagram of the upper receiver but I cant find the detailed instructions on how to do it. Can someone help me I'm attempting to build my first A-2 upper receiver!! Next week I'll tackle the barrell install

Do you mean how to install the forward assist and the ejection port cover?

If so, the only thing I have been able to find is the army/airforce manual (pdf). I haven't seen any online tutorials for those.

Get the Bushmaster video.

The only thing to install in the upper receiver is the forward assist, as Vector_Joe stated. It is a relatively simple procedure and should not require the purchase of a video. IIRC, you put the assist into place and drive in the roll pin.

The military manuals will cover this. The FA is simply putting the spring on the end, and puttin it inside the groove. Press in 3/8th of an inch or so, and tap in your pin. The ejection port cover is simple, but may take a few minutes of figuring which way the spring goes.

Its an A2 receiver so I also have to install the rear sight

As I said before-----get the video-----it covers all this and makes assembling the A2(or any other) upper receiver a no-brainer-------money well spent----my only regret is that I got the tape instead of the DVD.
