This red dot sight is powered by a solar panel, so you’ll never have to worry about batteries, and it features a 507C mounting plate that is compatible with most handguns. The red dot itself is extremely bright and easy to see, even in direct sunlight, and the ACSS Vulcan reticle provides an easy-to-see aiming point that will help you get on target quickly and accurately.

If you’re in the market for a fast and reliable red dot sight, the Holosun HE509-RD is a great option to consider. This pistol-sized sight provides a large field of view, making it quick and easy to acquire your target. Additionally, the rugged aluminum housing offers enhanced protection from the elements and potential impacts. So Whether you’re using it for competition, plinking or self-defense, the HE509-RD is a sight you can count on.


The adapter plate for the “-R” version is compatible with the most popular aftermarket slide cut in the industry. It is the same footprint as the Holosun 507C, making it compatible with most plate systems found on factory optics ready guns like the Walther PDP, S&W M&P C.O.R.E., CZ Optics Ready, Agency Arms AOS, FN 509 MRD, and Springfield Armory XDM Elite series handguns. It is also one of the most common aftermarket slide cut footprints.

The included 509 adapter plate is not compatible with ZEV or Shadow Systems style RMR interfaces.

The 509 ACSS model does not share the same footprint as the 509T (non-ACSS models) and therefore is incompatible with aftermarket mounting solutions and custom cut slides for the 509T (non-ACSS models).

The Holosun HE509-RD Enclosed Solar Powered Red Dot Sight w/ 507C Mounting Plate is a revolutionary new product that provides shooters with a large circle that guides their eyes towards the 10 MOA center chevron. This patent-pending reticle function significantly improves sight acquisition and makes it easier for shooters to find the center reticle. The sight also features a solar powered dot that can be easily deactivated to extend the battery life. This product is perfect for shooters who are looking for an easy to use sight that will improve their shooting accuracy.

The Holosun HE509-RD Enclosed Solar Powered Red Dot Sight w/ 507C Mounting Plate is a little powerhouse of an optic sight.

This sight features a solar powered LED that offers up to 20,000 hours of battery life, so you’ll never have to worry about changing batteries.
