HD118  Reflex Red Dot Sight.  This reflex sight features separate side-mounted physical switches for independent red and green illumination control, letting you quickly toggle between colors and cycle through multiple glove-friendly brightness levels suited for bright sun or low light. A base selector knob instantly switches between four sharp, stable reticle patterns for short and mid-range shots. It comes with a textured tool-free quick-detach mount that locks tight to standard 20mm rails with zero wobble, while clearly marked windage and elevation turrets offer tactile click adjustments to hold your zero steady through vibration and impact.
