Let’s Talk About Primary Arms Holosun HE509-RD Enclosed Solar
For years, I’ve relied on iron sights and open-emitter red dots, but always felt something was missing. That “something” was the peace of mind knowing my optic was protected from the elements and impacts. Enter the Primary Arms Holosun HE509-RD Enclosed Solar, a pistol-sized red dot that promised ruggedness and enhanced target acquisition.
I was specifically looking for a red dot that offered both a clear field of view and outstanding durability. I wanted something that could withstand the rigors of daily carry and the occasional bump in the field. My experience with open-emitter red dots left me wanting more protection.
Upon unboxing, the Primary Arms Holosun HE509-RD Enclosed Solar impressed me with its solid aluminum construction. The weight felt substantial, but not overly heavy for a pistol optic. It felt like a serious piece of kit designed to withstand some abuse.
I considered other enclosed red dots, such as the Aimpoint ACRO series and the Holosun 509T. I ultimately chose the Primary Arms Holosun HE509-RD Enclosed Solar because of its ACSS Vulcan reticle and compatibility with the Holosun 507C footprint. The Vulcan reticle is an incredible benefit! I wanted something that would help me rapidly acquire targets, and it seemed the best suited to meet my needs.
My first impression was excitement mixed with a healthy dose of skepticism; could this optic truly live up to the hype and solve my red dot woes?
Real-World Testing: Putting Primary Arms Holosun HE509-RD Enclosed Solar to the Test
First Use Experience
My first range trip with the Primary Arms Holosun HE509-RD Enclosed Solar was an eye-opener. I mounted it on my Glock 19 using a compatible adapter plate and headed to the outdoor range. The weather was overcast with a slight drizzle, conditions that typically plague open-emitter optics.
The Primary Arms Holosun HE509-RD Enclosed Solar performed flawlessly. The enclosed design kept the lens clear, and the ACSS Vulcan reticle provided rapid target acquisition, even in the dim light. I had no trouble finding the center aiming point, even when presenting the pistol quickly.
The ease of use was immediately apparent; after a quick zeroing session, I was consistently hitting targets at various distances. There was almost no learning curve! The crisp reticle and intuitive brightness settings made it a breeze to use. The only slight surprise was how much larger the window felt compared to open-emitter optics.
Extended Use & Reliability
After several months of consistent use, the Primary Arms Holosun HE509-RD Enclosed Solar has proven to be incredibly reliable. It has become my go-to optic for daily carry and training. The durability has been outstanding, with no noticeable signs of wear and tear despite being subjected to daily use and exposure to the elements.
I’ve carried it in various weather conditions, including rain, snow, and extreme heat, without any issues. Cleaning is simple. I use a lens pen and a microfiber cloth to keep the glass clear and free of debris.
Compared to my previous experiences with open-emitter optics, the Primary Arms Holosun HE509-RD Enclosed Solar outperforms them in every way. It offers superior protection, enhanced visibility, and improved accuracy in a variety of conditions. I also love the solar backup!
