Description
Most Holosun greens are pistol-sized; this one is not. The Holosun HE510C-GR Green Dot Sight is a rifle optic — a large open reflex with a 0.91 × 1.26 in window that stays forgiving with both eyes open. Its Multi-Reticle System gives you a 2 MOA green dot, a 65 MOA circle, or the two together, and it ships on a quick-detach mount at 1.41 in lower-1/3 co-witness height.
How It Compares
The same sight with a red emitter is the HS510C. To buy it already paired with a magnifier, see the HS510C + HM3X combo. There is more in rifle dot sights, and how to co-witness covers setting it up over irons.
Also available in: Tan.
Ideal For
- AR-15 and carbine builds
- Lower-1/3 co-witness over iron sights
- Shooters who want a green reticle on a rifle

Help & guidance
Product FAQs
Do I need to buy a mount for the HE510C-GR?
No. A quick-detach mount at 1.41 in lower-1/3 co-witness height comes in the box with the HE510C-GR.
When would I use the circle instead of the dot on the HE510C-GR?
The 65 MOA circle is the fastest thing to find up close, while the 2 MOA dot is the precise hold. You can run them together as a circle-dot if you want both at once.
How fine are the adjustments on the Holosun HE510C-GR?
Adjustment is half-MOA per click, with plus or minus 50 MOA of total travel in windage and elevation.
Should I choose the red or green HE510C?

What comes in the box with the HE510C-GR?
