The Holosun HE407C-X3-GR 2 MOA Green Dot Open Solar Pistol Reflex Sight is a specialized electro-optic system engineered to deliver rapid target acquisition and long-term operational reliability for everyday carry, duty, and tactical applications. A primary operational limitation when deploying traditional red dot sights in bright ambient environments or against complex backgrounds is reticle washout, which causes visual delay and eye strain. Holosun resolves this acquisition bottleneck by utilizing a 540nm high-visibility green LED light source, capitalizing on the human eye's natural sensitivity to green wavelengths for superior reticle contrast.
Constructed from forged, hard-anodized 7075-T6 aircraft-grade aluminum, this open-reflex sight is built to withstand violent slide reciprocation, 5,000 G recoil shock, and IP67 waterproof immersion. Engineered on the industry-standard Trijicon RMR footprint, it mounts directly to a wide array of optics-ready handgun slides and custom-milled setups without requiring proprietary adapter plates.
Designed to maximize power efficiency, the sight combines Solar Failsafe technology with Shake Awake motion activation. The dual-power setup dynamically draws ambient light while preserving the side-loading CR1632 battery, yielding an operational runtime of up to 100,000 hours. An expansive 0.91" x 0.63" window, combined with 12 brightness settings, automatic photodiode adjustment, and programmatic button lockout, ensures consistent reticle visibility in any shooting environment.
Key Benefits
- High-Visibility 540nm Green LED: 2 MOA green dot picks up faster in peripheral vision for rapid target tracking and high contrast against bright or complex backgrounds.
- Industry-Standard RMR Footprint: Mounts directly to factory optics-ready slides, custom cuts, and aftermarket setups without proprietary adapter plates.
- Solar Failsafe & Motion Activation: Dual-power solar system paired with Shake Awake auto-wake delivers up to 100,000 hours of continuous operational runtime.
- Side-Access Battery Tray: Allows fast CR1632 battery swaps without unmounting the optic or disrupting the firearm's established zero.
