Let’s Talk About Primary Arms GLX 2X Prism Red Dot Sight
The Primary Arms GLX 2X Prism Red Dot Sight is a compact, fixed-power optic designed for rapid target acquisition and enhanced accuracy at close to medium ranges. Manufactured by Primary Arms, this optic stands out due to its etched reticle, forgiving eye box, and rugged construction. I first heard about it from a colleague who swore by its performance in dynamic shooting drills.
I was in the market for a new optic to put on my 300 Blackout pistol. I had been struggling with traditional red dots due to my astigmatism, which caused the dot to appear blurry and starburst. The allure of a prism sight, with its etched reticle, promised a crisp, clear image regardless of my eye condition.
Unboxing the Primary Arms GLX 2X Prism Red Dot Sight was a pleasant experience. The optic felt solid and well-built, and the included mount seemed robust. The weight was noticeable but not excessive, and the overall design appeared compact and streamlined.
I considered the Vortex Spitfire AR and the Sig Sauer Bravo3, both popular 1x prism sights. I ultimately chose the Primary Arms GLX 2X Prism Red Dot Sight for its combination of 2x magnification, the ACSS reticle, and the promise of a brighter, more daylight-visible illumination. My initial excitement was high, hoping this optic would finally provide a clear and effective aiming solution.
Real-World Testing: Putting Primary Arms GLX 2X Prism Red Dot Sight to the Test
First Use Experience
I tested the Primary Arms GLX 2X Prism Red Dot Sight at my local outdoor shooting range. I mounted it on my AR-15 pistol chambered in 300 Blackout. The weather was sunny with a slight breeze, providing typical shooting conditions.
The optic performed exceptionally well in the daylight. The etched reticle was crisp and clear, even without illumination. The daylight bright illumination allowed for fast target acquisition even with the sun directly overhead.
Getting used to the 2x magnification took a few minutes, but I quickly adapted. The generous eye relief and forgiving eye box allowed for comfortable shooting from various positions. I experienced no significant issues during my first range session.
Extended Use & Reliability
After several months of regular use, the Primary Arms GLX 2X Prism Red Dot Sight has proven to be a reliable and durable optic. It has seen use in a variety of conditions, from sunny days at the range to rainy days during training exercises. The optic has held zero consistently, even after being subjected to rough handling.
The finish has shown minimal signs of wear, despite being bumped and scraped against various surfaces. Cleaning the lens is simple and straightforward, and the battery life has been impressive. It outperforms the red dots I’ve used in the past in clarity, but I must admit that the eye relief takes getting used to.
