[ARCHIVED THREAD] - Parts Needed for upper

Posted: 7/23/2009 11:55:29 AM EDT

I have a complete lower. Got a nice price on a RRA setup. But now money is tight and I want to be able to buy the rest piece by piece.

Is there a complete list of upper parts? I want a basic A2 / M4 setup. While it may cost more to buy each piece separately, it will ensure
I get exactly what I want and it won't seem like such a big hit all at once.
