From 3gun competition, tactical applications, or close range hunting, the new Cronus BTR GEN2 1-624 UHD is just what the doctor ordered. Rated as one of the best LPVO (Low Power Variable Optic) scopes, the ATSR2 SFP IR MOA reticle is specifically designed for 3 gun competition and tactical applications. With hold over points for both bullet drop and wind compensation, the ATSR2 reticle is designed for 68 and 69 grain BTHP 223 Rem/5.56mm NATO rounds. It is also suitable for many other bullet weights in these calibers. The 1.4 moa red dot is perfect for zeroing your rifle scope at 200 yards and the open centers below the center red dot are for targets at 300, 400, 500, and 600 yard. The unique design of open centers eliminates target obstruction with 12~18 inch targets beyond 200 yards, allowing a shooter to take a quick shot. The openings on horizontal lines below the center are specially designed for holding over 5 mph and 10 mph wind.
