Most people think of the DeltaPoint Pro as a pistol sight, but it is just as capable on an AR platform as it is on a handgun. The CQ DP-Pro Iron Sight co-witnesses with the red dot for continued functionality in the rare case of a battery failure. Leupold's extensive line of DP-Pro mounts will help you get the most out of this extremely versatile sight. It provides a second aiming point with a wide field of view. *Note- This is the Iron Rear sight for the DeltaPoint Pro.
