The March GENESIS scope is no ordinary rifle scope. Traditional rifle scopes are designed and constructed with an internal assembly which moves the image of the reticle and field of view as the turrets are adjusted. For long range shooting, the FOV is shifted far enough off the centerline of the lenses that optical resolution is reduced. Unfortunately, it is at long ranges where the shooter needs the best clarity. Long range shooters often use MOA inclined rail below their scopes, not just to provide more elevation adjustment but to keep the reticle closer to the optical centerline of the lenses when sighted in at long range. In the GENESIS scope, the reticle remains fixed, so it is always optically centered within the internal lens assembly of the scope, thus maximizing optical clarity in all conditions.
