The AR-536 is a compact, fast-acquisition optic designed for lawmen, military personnel, and competitive shooters who want additional range.The red or green illuminated reticle provides nanosecond response to immediate targets. It also allows for careful shooting at distant threats. A rotary, 10-position power selector accommodates all lighting conditions. The reticle runs on one CR2032 battery. The Ballistic CQ reticle features holdover dots good out to 600 yards. They work best with 5.56 or 7.62 ammunition. Picatinny rails allow piggybacking of additional sights, lasers or lights.
