The MG Kemper XL Machine Gun Reflex Sight from Firefield is an unmagnified aiming device for close-range targeting. This oversized reflex sight features a selectable green or red BDC reticle, each with five reticle brightness settings. The green reticle is more visible in twilight and low-light conditions than the red, but the red reticle is useful when targeting subjects set against a woodland backdrop. An oversized sighting window will assist target acquisition and be more effective than a standard-sized reflex sight when used to track rapidly moving targets. The MG Kemper XL has an integrated two-piece Weaver mount and is suited for heavy-caliber firearms and rapid fire shooting.
