You know, gas guns get a bit of a bad rap. If put together properly, built properly, set up properly, and matched up with ammo that it likes (hardest part of all in my opinion) then a lot of gassers will shoot better than most people can shoot them. I have a few that are .5MOA easily with me on them and would probably be even better with someone better handling them. Looks like that 6mm ARC proves my point.
