The HE503R-GD combines Holosun's Super Gold LED with Multi-Reticle System technology that gives you the choice of 2 MOA dot or 65 MOA circle with dot to create a highly effective and efficient Micro Optical Sight for rifle and carbines. The gold reticle offers a number of advantages over red or green: where red can get washed out against red or brown backgrounds and green can be ineffective in vegetation, gold stands out in both. The HE503R-GD employs ultra-efficient red LED technology that squeezes up to 100,000 hours of life from a single battery. It also features Holosun's new rotary switch that replaces the inch+ inch and inch- inch buttons on older models to make toggling reticles and brightness levels easier and quicker. It includes both a lower 1/3 cowitness mount and a low-profile mount, so you have some flexibility to fit your preference.
