Equip this Holosun green dot sight to quickly and accurately acquire targets during shooting exercises and in the field. Holosun built these Red Dot Sights with tons of innovative tech and features to improve your shooting experience. Solar Failsafe provides the HE407C X2 with a backup power source so that you can have a visible point of aim even if your batteries die. However, that event should be unlikely since you can get up to 50,000 hours of battery life, and Shake Awake technology preserves your power supply until the exact moment you need it. The HE407C X2 green dot sight features a green Super LED that offers better power efficiency than red LEDs, and green dot sights can be a better option for those who have difficulty seeing the color red. Multilayer coatings create a bright and brilliant sight picture, and you can choose from 12 different brightness intensities to best suit your needs and environmental conditions. Plus, 2 of those illumination settings are compatible with night vision goggles. Improve your aim during close to mid-range engagements with this compact yet powerful Holosun HE407C X2 pistol optic w/ green reticle.
