Griffin Armament M2 Micro Modular Rear Sight Review

Let’s Dive into Griffin Armament M2 Micro Modular Rear Sight

The Griffin Armament M2 Micro Modular Rear Sight is a compact, robust, and versatile aiming solution designed for AR-15 platforms. This rear sight, manufactured by Griffin Armament, distinguishes itself with its modular design, allowing for both standard 12 o’clock and ambidextrous 45-degree mounting configurations. Its low profile and durable construction make it an appealing option for shooters seeking a reliable backup or primary sighting system.

My journey to acquiring the Griffin Armament M2 Micro Modular Rear Sight began with a quest for a truly low-profile backup iron sight (BUIS) for my AR pistol. I wanted something that wouldn’t interfere with my red dot optic and could be quickly deployed when needed. I was particularly drawn to its modularity; the ability to potentially switch it to a 45-degree offset intrigued me.

Upon receiving the Griffin Armament M2 Micro Modular Rear Sight, I was immediately impressed by its solid feel and compact size. The QPQ treated 17-4 ordinance grade steel felt incredibly robust, inspiring confidence that it could withstand significant abuse. Its low-profile design was even sleeker than I had anticipated.

I was also considering the Magpul MBUS Pro and the Midwest Industries Combat Rifle Sight. However, the Griffin Armament M2 Micro Modular Rear Sight won me over with its lower profile and the intriguing modularity. I was hoping its quality and low profile would surpass my expectations, and early on, I was excited.

Real-World Testing: Putting Griffin Armament M2 Micro Modular Rear Sight to the Test

First Use Experience

I first tested the Griffin Armament M2 Micro Modular Rear Sight at my local outdoor shooting range. The conditions were typical for a summer afternoon: hot and slightly humid. I mounted the sight on my AR pistol and zeroed it at 50 yards.

The sight performed admirably, holding its zero even after several magazines of rapid fire. The adjustments were crisp and precise, and the sight picture was clear and easy to acquire. Flipping the sight up and down took a bit of effort initially, but it loosened up slightly with use.

The most immediate issue after first use was the stiffness of the deployment, which required a deliberate push to lock into place. However, this was a minor inconvenience compared to the overall solid feel and performance.

Extended Use & Reliability

After several months of regular use, the Griffin Armament M2 Micro Modular Rear Sight has proven to be remarkably durable. There are no signs of significant wear and tear, despite being exposed to various weather conditions and the normal bumps and scrapes of range use. The finish has held up well, and the sight continues to function reliably.

Maintenance is straightforward; a quick wipe down with a lightly oiled cloth after each range session is all that’s needed to keep it in good working order. The mechanism still requires a deliberate push to deploy, but it’s become smoother with continued use. Compared to other backup sights I’ve used, such as polymer Magpuls, the Griffin Armament M2 Micro Modular Rear Sight offers superior durability and a more robust feel.
