Looking for a top-tier sight for your rifle or carbine? The Holosun HE510C-GR is the Open reflex optical sight you need for speed and accuracy. This optic packs advanced features into a tough, open design, making it a favorite for tactical shooters and serious competitors alike.  

The HE510C-GR uses Holosun’s bright Green Super LED. Why green? Many shooters find the green color is much easier for their eyes to pick up, especially in bright daylight or complicated backgrounds. This sight is designed to work with your rifle right out of the box, offering fast target finding without compromise.  

This Holosun green dot is packed with features that keep you shooting longer and more accurately. The best part might be the long battery life—you get up to 50,000 Hours Battery Life on setting 6. That's years of run time! Plus, it has a Convenient Tray Battery Compartment that lets you change the CR2032 battery without taking the sight off your weapon.  

Key Features of the Holosun HE510C-GR

The Holosun 510C is more than just a Green Dot Sight. It gives you options with the Multi-Reticle System (MRS), letting you switch between three different aiming points to match your shooting needs:

• Green MRS: Choose from the Circle Dot (a 2 MOA Dot inside a 65 MOA Circle), the crisp 2 MOA Dot alone, or just the 65 MOA Circle.  
• Up to 50,000 Hours Battery Life (Setting 6).  
• 12 Brightness Setting: Includes 10 settings for daylight use (10 DL) and 2 settings compatible with Night Vision (2 NV Compatible).  
• Parallax-free & Unlimited Eye Relief for fast, comfortable aiming.  
• Multilayer Reflective Glass for a bright, clear picture.  
• Shake Awake™: This smart feature turns the optic off when it's still, saving battery, and instantly turns it back on when it senses movement.  
• Solar Failsafe™: Uses a small solar panel to power the sight when you have enough light, or acts as a backup if the battery is low. This ensures your Open Reflex Sight is always ready.  

You also get everything you need to mount it right away, including the Absolute Cowitness QD Mount, a T10 L Key, a CR2032 Battery, a Lens Cloth, and the User Manual.
