Let's get a little more perspective on what the OP really wants. An accurate complete upper in the $650-$800 price range. I'm sure a custom smithed "top notch" barrel is not what he's looking for. Also, show me a complete WOA upper in that price range.
Actually, most of WOA's uppers fall into that or very near, that price range...............mainly the ones that don't have Bartlien barrels.
Most are a pretty good deal, IMHO.
