Primary Arms GLx Cantilever Scope Mount, 34mm, 20 – 1 out of 2 models Review

What Makes Primary Arms GLx Cantilever Scope Mount, 34mm, 20 – 1 out of 2 models Stand Out?

The Primary Arms GLx Cantilever Scope Mount, 34mm, 20 MOA is more than just a piece of metal; it’s a crucial link in the chain of accuracy for any serious rifle shooter. This mount, designed and manufactured by Primary Arms, promises to deliver a robust and reliable platform for mounting your favorite 34mm scope. Its 20 MOA cant is specifically designed to enhance long-range shooting capabilities, a feature that immediately grabbed my attention.

My journey to this mount stemmed from a frustrating experience with a previous, less-than-stellar mount that constantly shifted zero on my AR-15. I needed a solution that offered rock-solid stability and the ability to effectively utilize the full potential of my long-range scope. This model promised both, and the reputation of Primary Arms for quality and value made it a compelling option.

Upon unboxing, the Primary Arms GLx Cantilever Scope Mount made a strong first impression. The black anodized finish looked flawless, and the mount felt substantial in my hand, inspiring confidence in its durability. The skeletonized rings hinted at a thoughtful design aimed at reducing unnecessary weight, a welcome feature.

Compared to other mounts I’ve used, like those from Aero Precision and Leupold, the GLx seemed to strike a better balance between weight, strength, and features. While the Aero mounts are exceptionally lightweight, they sometimes lack the robust feel needed for larger caliber rifles. The Leupold mounts, while known for quality, often come with a significantly higher price tag. I picked the GLx because it seemed to offer a sweet spot in terms of features and build quality at a reasonable price point.

My initial excitement was a mix of anticipation and cautious optimism. Past experiences with scope mounts had taught me that looks can be deceiving, and the true test would come at the range. Still, the initial impression was positive, and I was eager to see if the Primary Arms GLx Cantilever Scope Mount could live up to its promises.

Real-World Testing: Putting Primary Arms GLx Cantilever Scope Mount, 34mm, 20 – 1 out of 2 models to the Test

First Use Experience

My first outing with the Primary Arms GLx Cantilever Scope Mount was at a local shooting range known for its 500-yard steel targets. I mounted the GLx on my AR-15, topped it with a Primary Arms SLx 5-25x56mm scope, and proceeded to zero at 100 yards. The process was straightforward, with the mount easily clamping onto the Picatinny rail and the scope securely seated in the 34mm rings.

Conditions were fairly standard for a Texas summer day: hot, humid, and dusty. I was particularly interested to see if the mount would maintain zero despite the heat and the potential for dust to work its way into the threads. After the initial zeroing, I moved to the 300-yard range and began dialing in my corrections using the scope’s elevation turret. The 20 MOA cant of the mount immediately proved its worth, allowing me to easily reach the longer distances without maxing out my scope’s internal adjustment.

The mount performed flawlessly during the first session. There was no noticeable shifting or loosening, and the scope remained firmly in place. Even after repeated firing, the zero remained consistent.

Extended Use & Reliability

After several months of consistent use, the Primary Arms GLx Cantilever Scope Mount has proven to be remarkably reliable. I’ve used it in a variety of conditions, from hot and dry range days to moderately cold and wet hunting trips. The mount has held up admirably.

I haven’t noticed any signs of significant wear and tear. The anodized finish has resisted scratches and fading, and the steel hardware shows no signs of corrosion. Cleaning has been simple, usually just requiring a quick wipe down with a lightly oiled cloth.

Compared to my previous experiences with less expensive mounts, the Primary Arms GLx Cantilever Scope Mount is in a different league. It inspires confidence, and allows me to focus on shooting rather than worrying about whether my scope is going to stay put. The stability and zero retention are exceptional.
