The Valken Molded Red Dot Sight is an airsoft optic that comes with dual mounts. The reflex sight has a strong molded polymer housing, and mounts onto either a 3/8” dovetail rail or groove receivers, or most 20mm weaver rails. This airsoft red dot comes with a CR2032 battery to illuminate the 5 MOA red dot. We recommend our Valken Sight Protector Kit for use with this red dot sight.
