The Holosun HM3X is a 3X magnifier designed to extend the capability of red dot sights on rifles and carbines, providing additional magnification for target identification and precision at distance while allowing rapid return to an unmagnified sight picture. Its ambidextrous flip-to-side quick-detach mount makes the transition between 1X and 3X fast, while the included spacer supports both absolute and lower 1/3 co-witness optic heights. A 7-degree field of view, 2.75-inch eye relief, adjustable diopter, and precision windage and elevation adjustments help provide a clear and properly aligned sight picture. The sealed, nitrogen-purged aluminum housing provides IP67 water resistance for use in demanding conditions.
