HOLOSUN HE510C-GR & HM3X Combo – Green Dot Reflex Sight + 3x Magnifier

Elevate your aiming with the HOLOSUN HE510C-GR & HM3X Combo, a compact open reflex sight paired with a 3x magnifier. This system is designed for fast target acquisition, versatile ranging, and dependable field performance across hunting, competition, and outdoor shooting.

The HE510C-GR features an aluminum housing with a protective titanium hood, delivering a rugged, weather-ready silhouette. A green SuPer LED powers visibility with remarkable efficiency, offering up to 50,000 hours on a single CR2032 battery. Smart power features include Solar Failsafe and Shake Awake, helping the optic stay ready when you need it.

Smart power and bright, adaptable sighting

In bright light, the Solar Failsafe mode automatically adjusts reticle intensity to keep the aiming point crisp. When light fades or shifts, Shake Awake reactivates the LED at the first touch. Ten daylight levels and two night-vision-compatible levels give you room to tailor visibility to your environment.

Flexible reticle system for fast decisions

The Multi-Reticle System (MRS) lets you choose among a compact 2 MOA dot, a bold 65 MOA circle, or a combination of both. Use the circle as a reference for distance estimation and target spotting, then switch to the uncluttered 2 MOA dot for precise follow-up shots.

• Reticle options: 2 MOA dot, 65 MOA circle, or combined
• Green 540 nm illumination for clear daytime visibility
