Holosun unveiled its new Advanced Enclosed Micro Sight (AEMS) at this year’s Primary Arms Range Day, and product reps at the event described the rugged little optic as a “best of both worlds” between size, weight, and field of view.
The company has expanded beyond its initial lineup of products over the last few years to offer a variety of high-end options, and the AEMS fits neatly in that category. At $470-$505 MSRP, the AEMS ain’t cheap, but it comes with all the features we’ve come to expect from quality optics.
The AEMS features a 2 MOA dot reticle encompassed by a 65 MOA circle to allow for both precision work and snap shooting. The reticle can also be adjusted to show only the central dot, only the outer ring, or both the dot and outer ring.
The ShakeAwake feature turns the optic to the last brightness setting as soon as it’s moved (eight daylight, four night vision settings), and the 50,000 hours of battery life means you won’t have to change the CR2032 battery very often.
The AEMS is clearly designed for durability. The optic is rated to function between -30˚C and ~60˚C, can be submerged deeper than one meter (IPX8), and comes in a rugged, black anodized housing constructed from 7075 aluminum.
That housing features flip-up windows that can be flipped down for maximum clarity or kept up for greater protection. We didn’t notice any difference between viewing the reticle with the lens covers up or down. Those windows are also user-serviceable—if they break, the user can remove them and replace them using two simple screws.
The AEMS can be mounted directly onto a picatinny rail for a height of 1.02 inches above the rail. It also comes with a high-rise mount, which bumps that height up to 1.63 inches. Holosun’s footprint is proprietary, which means it can’t be used with any other company’s mounts.
The optic is obviously built like a tank, but it only weighs 3.9 ounces and measures 2.2×1.54×1.7 inches. The window size measures 0.87×1.1 inches, but the nearly square shape gives it a greater field of view than you might expect.
Holosun has not published field of view numbers on its website, and the product rep we spoke with couldn’t recall them at the event. But looking through the optic, it’s easy to see that the AEMS boasts a huge field of view for a reflex sight of this size. We had no trouble keeping the reticle on target while shooting full-auto with this IWI Galil.
That healthy field of view, combined with the optic’s durability, crisp reticle, and ease of use, should make the AEMS a strong contender for your next rifle optic.
