Real-World Testing: Putting Primary Arms Holosun HE509-RD Enclosed Solar Powered Red Dot Sight to the Test

First Use Experience

My first outing with the HE509-RD was at my local shooting range. The goal was to zero the optic on my Glock 19 and get a feel for the ACSS Vulcan reticle. The weather was overcast with a light drizzle.

Even in the somewhat dim lighting, the red chevron and outer circle of the ACSS Vulcan reticle were bright and clear. Sighting in was straightforward, with the 1 MOA adjustments providing precise control. The large field of view made target acquisition intuitive, and the enclosed emitter design seemed unaffected by the light rain.

The only initial issue was adjusting to the reticle. Accustomed to standard dots, I needed some time to fully appreciate the benefits of the outer circle for guiding my eye.

Extended Use & Reliability

After several months of consistent use, the Primary Arms Holosun HE509-RD Enclosed Solar Powered Red Dot Sight has proven its reliability. I’ve used it in various conditions, from sunny days at the range to low-light scenarios during tactical training exercises. It has performed admirably every time.

The optic has held zero perfectly, even after hundreds of rounds and some accidental bumps. There are no noticeable signs of wear and tear on the housing or lens. Cleaning is simple. A quick wipe with a microfiber cloth keeps the lens clear of dust and debris.

Compared to open-emitter red dots I’ve used previously, the HE509-RD is a significant improvement. The enclosed design virtually eliminates concerns about dirt or moisture interfering with the emitter. This is a crucial advantage for anyone who relies on their firearm for self-defense or professional use.
