I don't have any Wilson Combat barrels or uppers, so I can't comment there. I think I have some Aero precision stuff, lightweight scopemounts come to mind. Have a few and like them.
I bought a complete upper from Larue and I really like it. I bought this one a while back when they were on sale last year for about $700-800 if I remember correctly.
