Holosun HE510C-GR-FDE 510 1x 0.91" x 1.26" 2 MOA Green Dot/65 MOA Circle Multi-Reticle Reflex Sight - Flat Dark Earth

The Holosun HE510C-GR-FDE is a versatile open reflex optic engineered for long gun use, right at home on carbines, PCCs, and shotguns. This FDE-finished variant brings the proven 510 Series feature set to a Flat Dark Earth housing that blends naturally with desert and earth-tone rifle builds.

The multi-reticle system pairs a precise 2 MOA green dot with a 65 MOA green circle, so the shooter can dial in for fine aiming at distance or switch to a fast circle-dot pattern for close-range work. The wide 0.91" x 1.26" objective window provides a generous sight picture with unlimited eye relief.

Built around a rugged aluminum housing and multi-coated glass, the HE510C-GR-FDE runs on a single CR2032 battery with an industry-leading 50,000-hour runtime. Brightness is handled by 10 daylight and 2 night vision settings, so the optic is ready to pair with night vision setups. The 0.5 MOA click value makes windage and elevation adjustments easy to track and call.

At 1x magnification, the optic measures 3.30" long and weighs just 4.94 oz. The HE510C-GR-FDE is rated waterproof, fully adjustable for windage and elevation, and ready to mount on a wide range of long guns right out of the box.
