Product Overview
Overview
The Holosun HE509T RD X2 Red Dot Sight is an enclosed-emitter red dot sight with a red reticle. Dot size is 2 MOA dot / 32 MOA circle. Multi-Reticle System (MRS): 2 MOA dot, 32 MOA circle, circle-dot.
Fitment
This uses the Proprietary Holosun 509T footprint. Holosun list it as fitting: 509T-cut slides directly, RMR-pattern slides via the included RMR-to-509T adapter plate. 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.
