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.
