Details
Description
One of Holosun's most-owned rifle optics, the Holosun HS510C Red Dot Sight pairs a wide, square 0.91 × 1.26 in window — quick and forgiving with both eyes open — with the Multi-Reticle System. A button press gives you a 2 MOA red dot, a 65 MOA circle, or both at once as a circle-dot, so close-range speed and longer-range precision live in the same optic.
How It Compares
The green-emitter version is the HE510C-GR. To buy it already matched to a magnifier, see the HS510C + HM3X combo. More options sit in rifle dot sights, and how to co-witness covers setting it up over irons.
Also available in: Tan.

- AR-15 and carbine builds
- Both-eyes-open shooting behind a large window

Help & guidance
Product FAQs
Does the Holosun HS510C come with a mount?
Yes, the HS510C includes a quick-detach mount at 1.41 in lower one-third co-witness height. That makes it ready for a flat-top rail straight out of the box.
Which reticle should I use on the HS510C?
On the Holosun HS510C the 65 MOA circle is the quickest to find up close, the 2 MOA dot is the precise hold, and the circle-dot gives you both together. A button press moves between them.
Will the HS510C take a magnifier behind it?
Yes, the Holosun HS510C will run with a magnifier behind it, and it is also sold already matched to the HM3X in a combo. The wide window suits both-eyes-open shooting at 1x.
Is there a green version of the HS510C?
Yes, the HE510C-GR is the same sight with a green emitter. The HS510C described here is the red-emitter model in black.
How big is the window on the Holosun HS510C?
The HS510C has a wide, square viewing window of 0.91 x 1.26 in, which is 23 x 32 mm. That large window is quick and forgiving with both eyes open.
What battery does the Holosun HS510C use?
The HS510C runs on a CR2032 battery rated up to 50,000 hours. Solar Failsafe backs it up and Shake Awake stands the sight down when it is still.
What are the click values on the HS510C turrets?
The Holosun HS510C uses fine 0.5 MOA clicks for windage and elevation. Total adjustment travel is plus or minus 50 MOA in both axes.
Is the HS510C waterproof?
The Holosun HS510C has an aluminium housing with an IP67 rating. It is built for AR-15 and carbine use.
Does the HS510C co-witness with iron sights?
Yes, the Holosun HS510C mount sits at 1.41 in, which is lower one-third co-witness height over iron sights. The quick-detach design lets you remove and refit it.
Is the Holosun HS510C magnified?
No, the HS510C is a 1x sight that is parallax-free with unlimited eye relief. Magnification can be added by placing a magnifier behind it.
What colours does the HS510C come in?
The Holosun HS510C is offered in black and also in tan. Both share the same Multi-Reticle System and quick-detach co-witness mount.
