I just put together an 18" 6 ARC. Using an Aero Precision Enhanced M4E1 upper with a JAG composite CF handguard and an 18" Rainier Arms Match barrel. I also have a 16" using the same upper and handguard. The target pic was taken during the zeroing. All of the Rainier barrels I own are MOA or better...I have a 18" Rainier Arms match barrel, Toolcraft BCG, and Superlative AGB on their way to convert one of my AR's to 6ARC.
