Valken Optics 1x35 Multi-Reticle Red Dot Sight. The Valken 1x35 Multi-Reticle 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, and comes with multiple reticles in both red or green illumination. 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.
