Holosun HE407C-X3 2 MOA Green Solar - Red Dot Sight

When your everyday carry or duty pistol needs a fast, smart red dot that never lets you down, the Holosun HE407C-X3 Green 2 MOA delivers a crisp green dot, Solar Failsafe power management, and IP67 waterproofing in a hardened 7075-T6 aluminum housing sized for the RMR footprint.

The Holosun HE407C-X3 is a pistol red dot sight designed for EDC, duty, and competition shooters who want a reliable, feature-rich open reflex sight with a green 2 MOA dot, solar backup power, and Shake Awake convenience built around the industry-standard RMR mounting footprint.

The X3 generation of the 407C upgrades the housing with reinforced construction and advanced brightness management, starting with a forward-facing photodiode that continuously reads ambient light and automatically adjusts dot brightness to match conditions — so the dot is always visible without manual adjustment in changing light. Solar Failsafe technology keeps a parallel solar cell running alongside the battery, providing a backup power source in any environment where natural or artificial light is available, dramatically extending effective battery life in real-world use. The side-loading CR1632 battery tray lets you replace the battery without removing the optic from the slide — a practical detail that matters on a carry gun. Shake Awake with memory and lockout ensures the sight activates instantly on the draw and powers down automatically when left still, while lockout mode prevents inadvertent brightness changes in the field. At 1.55 oz in a 7075-T6 aluminum housing, the HE407C-X3 adds virtually no felt weight to a carry or duty pistol.

RMR footprint compatible with most modern MOS, MRDS, and optic-cut pistol slides. Adjustment: 1 MOA per click, ±50 MOA travel. Window size: 0.91×0.67". Dimensions: 1.78×1.31×1.1". Weight: 1.55 oz. IP67 waterproof. 5000G vibration rated. 8 daylight + 4 night-vision brightness settings. Battery life: up to 100,000 hours (CR1632, setting 6). Wavelength: 540nm green.

The 7075-T6 aluminum housing with hard anodize surface finish provides excellent impact resistance and corrosion resistance for carry and duty use. Multi-coated glass delivers a clear, distortion-free sight picture across all brightness settings.

An outstanding choice for everyday carry pistols, duty handguns, competition setups, and any RMR-footprint pistol where a crisp green dot, smart power management, and proven Holosun reliability are the priorities.
