Primary Arms GLx Mini Reflex Sight, ACSS Vulcan Review

What Makes Primary Arms GLx Mini Reflex Sight, ACSS Vulcan Stand Out?

In a world saturated with red dot sights, the Primary Arms GLx Mini Reflex Sight, ACSS Vulcan emerges as a beacon of innovation. This optic, from the reputable Primary Arms, isn’t just another aiming solution. The key feature that sets it apart is the ACSS Vulcan reticle, designed to significantly improve target acquisition speed and accuracy, especially for newer pistol shooters or those transitioning to red dots. It promised a faster learning curve and better performance under pressure, a claim I was eager to verify with my decade-plus experience.

For years, I’ve struggled to help new shooters quickly and efficiently zero and acquire targets with red dots, a persistent challenge in my training courses. I was looking for a reflex sight that could provide intuitive feedback and help overcome the common “dot drifting” problem. The Primary Arms GLx Mini Reflex Sight, ACSS Vulcan‘s innovative reticle seemed like the perfect solution to bridge that gap.

Upon unboxing, my first impression was of a robust and well-engineered piece of equipment. The housing felt solid, the glass was crystal clear, and the adjustment turrets had a reassuring click. Its compact size and weight suggested it wouldn’t add unnecessary bulk to a pistol slide.

Compared to other mini reflex sights I’ve used, like the Trijicon RMR and Holosun 507C, the Primary Arms GLx Mini Reflex Sight, ACSS Vulcan immediately stood out due to its unique reticle. While the RMR is known for its bombproof durability and the Holosun for its feature-rich design, both rely on the traditional single dot. I ultimately chose the Primary Arms GLx Mini Reflex Sight, ACSS Vulcan for the promise of faster target acquisition and intuitive use.

My initial excitement was tempered with cautious optimism. The ACSS Vulcan reticle was certainly unique and appeared to be well-executed. It remained to be seen how it would translate to real-world performance.

Real-World Testing: Putting Primary Arms GLx Mini Reflex Sight, ACSS Vulcan to the Test

First Use Experience

I mounted the Primary Arms GLx Mini Reflex Sight, ACSS Vulcan on my Glock 19 and headed to the shooting range for initial zeroing and drills. I tested it in sunny conditions as well as under the artificial lighting of an indoor range to assess clarity and visibility. Zeroing was surprisingly quick and easy, thanks to the clearly marked and tactile adjustment turrets.

The ACSS Vulcan reticle truly shined during rapid target acquisition drills. The large outer circle, designed to guide the eye to the central dot, immediately proved its worth. Even when presenting the pistol imperfectly, the circle made it simple to quickly find the reticle and make necessary adjustments. It was far more intuitive than the sometimes elusive single dot of other reflex sights.

There were no immediate issues, but I did notice that the outer circle could be slightly distracting at longer distances (beyond 25 yards). This was something I planned to address with further training and adjustment of the brightness settings.

Extended Use & Reliability

After several weeks of consistent use, including multiple range trips and dry-fire practice sessions, the Primary Arms GLx Mini Reflex Sight, ACSS Vulcan has proven to be a reliable and valuable addition to my carry setup. It has endured the vibrations of hundreds of rounds fired, as well as the bumps and scrapes of daily carry. There have been no signs of loosening or zero shift.

The optic shows minimal signs of wear and tear. The glass remains clear and scratch-free, and the housing exhibits no noticeable blemishes. Cleaning the lens is simple, and the battery life appears to be excellent so far.

Compared to my previous experiences with other reflex sights, the Primary Arms GLx Mini Reflex Sight, ACSS Vulcan offers a significant advantage in terms of ease of use and speed of target acquisition, especially for new shooters. It has definitely outperformed my initial expectations and I now recommend it to any shooter struggling with their red dot.
