The Valken Hooded Mini Red Dot Sight is a reflex sight for airsoft guns. The mini reflex red dot sight housing is molded from a glass-filled nylon polymer and mounts to most 20mm Picatinny and weaver rails. This tactical optic includes a CR2032 battery to illuminate the 5 MOA red dot and has an extended hood to protect the laser diode from dirt/dust and sun glare. This airsoft optic is a great reflex red dot for airsoft pistols or SMGs. We recommend our Valken Sight Protector Kit for use with this red dot sight.
