The standard German Army versions of the G36 are equipped with a ZF 3x4° dual optical sight that combines a 3x magnified telescopic sight (with the main reticule designed for firing at 200 m and bullet drop compensation markings for: 200, 400, 600 and 800 m
crosshairs and a range-finding scale) and an unmagnified
reflex sight (calibrated for firing at 200 m) mounted on top of the telescopic sight.
[2] The reflex sight is illuminated by ambient light during the day and uses battery powered illumination for use at night. Electric illumination is activated automatically by a built in photo sensor and can be manually activated to boost the brightness of the
reticle in daytime low contrast situations.
