Details
Description
Holosun HE510C-GR Green Dot Sight in Tan is the green-emitter version of Holosun's big open reflex sight — the HE prefix is what marks it out from the red HS510C. You look through a wide 0.91 × 1.26 in window with both eyes open, and the Multi-Reticle System gives you a 2 MOA green dot, a 65 MOA circle, or the two together: the circle for speed up close, the dot on its own when the shot needs care.
How It Compares
Prefer a red reticle? The HS510C is the same sight with a red emitter. Planning to run a magnifier behind it? Look at the HS510C + HM3X combo. There is more in our rifle dot sights, and how to co-witness covers height over bore and iron sights.
Also available in: Black.

Help & guidance
Product FAQs
What is the difference between the HE510C-GR and the HS510C?
The difference is the emitter, where HE denotes the green reticle and HS the red one. Some shooters find green easier to see in daylight, and otherwise the two are identical.
What does the Multi-Reticle System give me on the HE510C-GR Tan?
It gives three choices from one sight: the 2 MOA green dot alone, the 65 MOA circle alone, or both as a circle-dot. The circle is for speed up close and the dot on its own when the shot needs care.
Does the HE510C-GR Tan come with a mount?
Yes, a quick-detach mount at 1.41 in is included, which puts the reticle at lower-1/3 co-witness height over most AR-15 iron sights. No separate mount purchase is needed.
How is the HE510C-GR powered?
It runs Solar Failsafe alongside a CR2032 battery, with Shake Awake, rated up to 50,000 hours.
How tough is the HE510C-GR Tan?
The housing is aluminium with an IP67 rating. Zeroing is done in 0.5 MOA clicks with plus or minus 50 MOA of travel available in each axis.
How big is the window on the HE510C-GR Tan?
The viewing window is 0.91 by 1.26 inches, or 23 by 32 mm. That wide open window suits both-eyes-open shooting.
What magnification does the HE510C-GR have?
It is 1x, parallax-free with unlimited eye relief. If you plan to run magnification behind it, the HS510C is also sold as a combo with the HM3X magnifier.
What are the click values on the HS510C-GR-FDE?
Windage and elevation adjust in 0.5 MOA clicks. Total travel is plus or minus 50 MOA in each axis.
What comes in the box with the HE510C-GR Tan?
The box contains the Holosun HE510C-GR green dot sight in Tan, a quick-detach co-witness mount, and a CR2032 battery.
What colours does the HE510C-GR come in?
This sight is offered in Tan and in Black. The red emitter version of the same sight is the HS510C.
What rifles is the HE510C-GR Tan suited to?
It suits AR-15 and carbine builds, particularly ones finished in tan or FDE. It is set up for lower-1/3 co-witness with iron sights.
