If anyone is shooting with this what are your impressions? Im building a 20" AR. The barrel is the Noveske 20" Med. Varmint model. the BCG is a Y/M National match flavor and the trigger will be the Geissele Super 2 Stage whenever it comes out! I want a nice optic to go on top so can you guys shoot me some suggestions. The range will be out to 600yds. I dont have much experience shooting past 300 so Im trying to expand a little and get into a new arena of shooting.
