Griffin Armament 30mm Cantilever GPM 1.5″ Height 15MOA Mount Review

The Griffin Armament 30mm Cantilever GPM 1.5″ Height 15MOA Mount Made a Bold First Impression

In the dynamic world of precision shooting, a reliable optic mount is the unsung hero ensuring consistent accuracy. The Griffin Armament 30mm Cantilever GPM 1.5″ Height 15MOA Mount aims to be that steadfast foundation, marrying rugged durability with innovative modularity. Griffin Armament has a reputation for crafting high-quality components, and this mount seemed poised to deliver on that promise, sparking my interest and prompting a thorough evaluation.

My quest for a new mount arose from a persistent challenge: achieving reliable zero at extended ranges with my AR-15 platform. I needed a mount that could provide both a secure optic hold and a built-in elevation bias for long-distance shooting. Existing mounts often lacked the robust construction or the necessary MOA adjustment, leading me to explore the Griffin Armament offering.

The unboxing experience immediately revealed a product built with meticulous attention to detail. The mount felt substantial in hand, indicative of the high-grade materials and robust construction. Its sleek, matte-black finish hinted at its tactical pedigree, while the numerous mounting surfaces suggested unparalleled versatility.

Compared to other cantilever mounts I’ve used, such as those from LaRue Tactical and American Defense Manufacturing, the Griffin Armament mount stood out due to its Accessory Interface Suite (AIS™). The others, while solid, lacked this level of modularity. This innovative design convinced me that the Griffin Armament mount could offer a more tailored and adaptable shooting experience.

My initial impression was one of excitement tempered by cautious optimism. I was eager to test its performance and verify whether its innovative features translated into real-world benefits. This mount promised much, and I was ready to see if it could deliver on that promise.

Real-World Testing: Putting Griffin Armament 30mm Cantilever GPM 1.5″ Height 15MOA Mount to the Test

First Use Experience

I first tested the Griffin Armament 30mm Cantilever GPM 1.5″ Height 15MOA Mount at a local shooting range, specifically focusing on its performance with my AR-15 chambered in 5.56 NATO. The range provided a controlled environment with targets set at distances ranging from 100 to 600 yards. This allowed me to thoroughly evaluate the mount’s ability to maintain zero and its effectiveness in long-range shooting scenarios.

The weather conditions were less than ideal – a light drizzle and a persistent crosswind. These conditions presented a realistic challenge, testing the mount’s ability to hold zero despite environmental factors. The mount performed admirably, exhibiting no shift in zero even with the variable weather.

The mount was remarkably easy to install and adjust. The clear instructions and well-machined components made the mounting process straightforward, even for someone with moderate experience. After mounting my optic, a Vortex Razor HD Gen II, I found the eye relief and cheek weld to be perfect, thanks to the 1.5″ height of the mount.

One initial surprise was the stability afforded by the Stanag 4694 Compliant attachment. Even after repeated firing, the mount remained securely attached to the rail. The added height and forward placement created a more natural shooting posture, improving my overall comfort and control.

Extended Use & Reliability

After several months of consistent use, the Griffin Armament 30mm Cantilever GPM 1.5″ Height 15MOA Mount has proven to be exceptionally reliable. I have taken it through numerous range sessions, a precision rifle course, and even a multi-day hog hunt, where it encountered rough handling and adverse weather. Through it all, the mount has maintained its structural integrity and zero.

The mount shows virtually no signs of wear and tear, despite the extensive use. The Type 3 milspec hardcoat anodizing has effectively resisted scratches and abrasions, even when exposed to harsh environmental conditions. The robust construction gives me confidence that this mount will withstand years of hard use.

Cleaning and maintaining the mount is incredibly simple. A quick wipe-down with a solvent-dampened cloth removes any dirt or grime. The fact that the mount is constructed from 6061 T6 aluminum makes it corrosion resistant, further simplifying maintenance.

Compared to my previous mounts, this Griffin Armament mount significantly outperforms them in terms of modularity and zero retention. The added benefit of the AIS™ system for accessory attachments is a game-changer, allowing me to customize my rifle setup to suit various shooting scenarios. The built-in 15MOA elevation is also a welcome addition, enabling me to effectively engage targets at extended distances.
