Our single ring 30mm will accommodate a wide variety of red dot optics with 30mm tubes, most commonly the Aimpoint PRO and Comp M Series. The single ring 30mm mount weighs in at only 3.15 ounces and is manufactured with the same quality and durability you've come to expect from all Daniel Defense products.
