You don't have to tune anything at this point in the BO game. Buy quality parts from a reputable company and use the Barnes VorTX ammo. Pistol-length gas and just a plain-ol fixed gas block. I currently have barrels from Noveske and AAC that have both been flawless with that configuration. I'm running standard CAR buffers. I started out a BO skeptic, but am now a huge fan. Deer hunting with mine tomorrow, too.
What made you a huge fan?
