The Holosun HS503GU Sight features a unique side mounted battery and a U-housing design that covers the windage and elevation turrets on two sides. These Red Dot Sights utilize LED technology that enhances the battery life up to 5 years, and uses the Holosun Shake Awake technology to automatically turn the optic on when it senses movement, and shuts it back off automatically once the movement has subsided.

    Excellent sight. The circle dot is super fast. I wanted something to replace my Eotech, with the 65 MOA circle dot reticle, and this does the job at a great price. I haven't heaped any abuse on it yet, but it seems solid so far.

    Great sight and a great price offered from Botach. Product shipped within a reasonable time with no tax and no shipping charges. Very happy with this purchase
    I love the 65 MOA reticle. It helps with rapid acquisition of the target.
    The "shake awake" feature is another plus especially if your intentions are home defense.
