The CRONUS BTR GEN2 UHD 1-6x24 ATSR2 SFP IR MOA is a highly recommended Low Power Variable Optic (LPVO) scope suitable for activities such as 3-gun competition, tactical applications, and close range hunting. Its ATSR2 SFP IR MOA reticle is specifically designed for 3-gun competition and tactical applications, with bullet drop and wind compensation holdover points for 68 and 69 grain BTHP 223 Rem/5.56mm NATO rounds, as well as other bullet weights in those calibers. The 1.4 MOA red dot is ideal for zeroing at 200 yards, while the open centers below the center red dot are perfect for targets at 300, 400, 500, and 600 yards. The open center design eliminates target obstruction for 12-18 inch targets beyond 200 yards, allowing for quick shots. The horizontal lines below the center are specially designed for holding over 5 and 10 mph wind.
