Your note on Aero barrels re Ballistic Advantage is partially true, from my look it seems Aero and Ballistic Advantage became sister companies but neither is in direct ownership of the other? They do however use their barrels, as of about 2016 all Aero marked barrels are made by BA. I have one of their uppers with a BA made Aero 16” medium profile barrel and it is great. I also have a BA Hanson barrel and it is better, but you want fully built upper so maybe consider BA uppers as well.
