## Overview

The Holosun HE509-RD is a cutting-edge enclosed red dot sight featuring a solar-powered LED with 12 brightness settings and a patented ACSS Vulcan reticle. Designed for durability and precision, it offers up to 20,000 hours of battery life, Shake Awake technology for instant readiness, and broad compatibility with popular handgun mounts. Its rugged aluminum housing and enclosed emitter ensure reliable performance in all conditions, making it the ultimate optic for concealed carry and tactical training.

## Description

Notes: 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. 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 ACSS Vulcan reticle provides a large circle guiding the eyes towards the 10 MOA center chevron. If you are off-center, a portion of this outer circle will appear in the window to give you an instant reference on how to get centered. The circle phases out of the sight window completely when the center chevron is properly aligned in the sight window. Don't need the circle? It can be easily deactivated. The Holosun HE509 Red Dot Sight uses Solar Failsafe technology to power the optic and uses patented Shake Awake technology which senses motion to power the sight on and off. In addition, it “recalls” your last setting and makes sure you don’t lose those customized settings once the sight system turns off. The Holosun HE509 Red Dot Sight offers up to 20,000 hours of battery life. All versions of the Holosun Red Dot Sight system are projected from the same LED, so you don’t have to worry about having to re-zero when changing reticles. NOTE: This optic is not intended to allow co-witness of fixed iron sights EXPORT CONTROLLED ITEMS: These items are controlled for export and may require an export license from the U.S. Government.

Review: Excellent quality - I concealed carry, & do a lot of range training so an enclosed emitter like this one fit the bill perfectly. It's easy to keep free from lint & dust & the titanium housing is super durable. I over torqued my first one & sheared the screws but holosun sent me out a replacement set right away. Great customer service. Purchased a second one so my carry gun can match my training gun. Great optic for the money.
Review: No other red dots compare - So I was vastly skeptical about trying this HoloSun 509 ACSS red Vulcan reticle compared to my other reflex red dots because I wasnt sure how it would function on my P320 XCompact but also because I didn't want a gawkingly huge optic on my concealed carry. This thing never let me down at the range or in the field and looks absolutely amazing. The reticle doesn't get washed out in bright light because it utilizes the solar panels with the battery to automatically brighten the reticle or dim it when needed. You can brighten it dim it manually as well if you'd like. The reticle shuts off after 10mins of non-use and incporates shake-awake technology so it comes on when you pull it up and out of your holster. The chevron can be used to gauge your distance without guessing while aiming high for longer distances. It comes sighted in from the manufacturer and I tested that out with my bore sighter and again at the range. At 25yrds I hit 40/50 shots in my small orange/black target with slow firing. At faster pace firing at the same range I still hit between the 10-8 on the green B27 target. Then repeated the same fire rate on a single white sheet of paper. The optic is deadly and very fast to acquire target. Much faster than align rear and front iron sights, which I've done for over 30yrs. At the very tip of the chevron it's zeroed at 7 and 25yrds. At the inside bottom of the tip it hits 50yrds and between the two arms of the chevron at the bottom is 100yrds, beyond that it's a guess but with a pistol you'll never shoot that far. I love that the emitter is enclosed so it can't be obstructed by anything like snow, rain, dirt, etc. You can rack your gun using the optic off anything, even hard surfaces and really smack this thing around, drop it, bang it around and it still holds zero and works flawlessly. It's the perfect size for pistols and doesnt look big on the gun! It makes anyone's pistol more deadly and made my pistol look menacing! I love this thing! It comes with adjustment tools for the reticle, adapter plate and mounting tools. I had C&H precision send me a filler plate in place of the adapter plate to fill any tiny gaps between my slide and the optic. Phenomenal optic! I'll be getting one for each of my pistols and maybe even my shotgun. See the pictures for more details.

A: Thank you for your question. This red dot will come with the RMR/507C plate.

**Q: is this rmr footprint?**

### ⭐⭐⭐⭐⭐ Holosun perfection at its finest
*by L***T on November 16, 2025*

I love this optic. Worth every penny. You won’t be disappointed. Do yourself a favor and buy the C and H precision mounting plate. Glock plate are no good.
