Set a new performance standard with the Barska Optics Euro-30 Pro 3 - 12 x 50 Riflescope. With a medium power magnification range, the riflescope is ideal for big-game and general hunting. The wider field of view makes it easier to spot game and track moving targets. While in the field, your view will not be obstructed by breathing since the fully coated optics prevent fogging. Nor will a few rain drops affect your view since the scope stays dry on the inside in all weather conditions. Field of view: 35.2' - 11.7' at 100 yds. Exit pupil diameter: 16.8 - 4.2 mm. Tube length: 13.2". Tube diameter: 30 mm. Mounting length: 5.31". 21.5 oz. Requires one 3V Lithium battery (included).
