Ok heres my question. On the KAC EMC the new offset front sight is not set out to the front of the rail like they are when mounted on the SR15 or the M110. Is this to match the markings on the rear sight adjustment barrel to match the ballistics of the 7.62 ballistics? And if so what is the sight radius needed for the KAC Micro sights to track ballisticly to the 7.62 round?
