Product Overview

Overview

The Holosun HE510C GR Green Dot Sight is an open-emitter green dot sight with a green reticle. Dot size is 2 MOA dot / 65 MOA circle. Multi-Reticle System (MRS): 2 MOA dot, 65 MOA circle, circle-dot.

Fitment

This uses the Picatinny rail, integrated quick-detach mount footprint. Holosun list it as fitting: Picatinny/1913 rails - rifle optic, not a pistol footprint. Check your slide cut before ordering — footprints that look similar are not always interchangeable.

Parallax

Holosun call this a Parallax Free Optical System. In practice a reflex sight still shows a small point-of-aim shift off-axis at close range.

Warranty

Holosun's Limited Lifetime Warranty is split by component: the housing and glass are covered for the life of the product, while the LED illumination system is covered for 10 years from the date of manufacture rather than the date you buy it. Batteries are not covered, and Holosun require you to register the product for the warranty to be valid.

US Shipping & Support

Shipped from the USA by D&R Sports Center. If you are unsure which optic fits your slide or rail, ask us before you order — we would rather get it right first time.
