The Valken 1x35 Tactical Red Dot Sight is a tactical optic for airsoft rifles. The red dot sight has a 35mm objective lens, and comes with flip-up lens covers. This airsoft optic has a rotary illumination control knob to adjust reticle intensity with 5 different brightness settings. It also mounts to most 20mm picatinny and weaver rails, and comes with adjustable elevation and windage turrets. They also come with a coated lens that provides superior light transmission, resolution, and scratch resistance, and a 3 MOA reticle, which makes for excellent and rapid target acquisition. We recommend our Valken Sight Protector Kit for use with this red dot sight.
