rra uses wilson(nothing to do with the wilson company that makes 1911 and 1911 parts) air gauged cryogenic treated barrels in their varmint guns. i dont think you can beat the rra pricepoint for the quality precision uppers they make.
my personal opinion as to barrel length, anything over 20" serves no real purpose in a 5.56 .223
