The AR-332 is designed for lawmen, military personnel, and competitive shooters who want additional range from a compact, fast-acquisition optic. The rotary, 10-position power selector allows quick changes from red to green powered reticle, or clear, crisp black reticle when power is off. With five red and five green power levels, all lighting conditions can be quickly matched. A CR2032 battery powers the reticle. The Ballistic CQ? reticle features holdover dots good out to 600 yards. They work best with 5.56 or 7.62 ammunition.
