Holosun’s recently released Ronin AEMS Max red dot sight is making waves with the largest window, at least among major brands, on any rifle red dot right now. Let’s see if this new optic lives up to the hype.

Background

Holosun released its original Advanced Enclosed Micro Sight, or AEMS, in 2021. The concept was a lightweight optic with a large window. It had a bigger window than the Aimpoint T2 and was much lighter than an Eotech. Here's how these optics compare to the Ronin AEMS Max:
 

Not only was the window size comparable to that of an Eotech, but I feel it also had less obtrusive walls, leading to a less obstructed sight picture. In addition, the AEMS benefited from Holosun’s expertise at making rugged and reliable optics with excellent run times at an affordable price point. 
 

The final nice feature was the integrated transparent lens covers. They were always in place to protect your glass, and because you could see through them, they only needed to be flipped down when debris or mud obscured the optic.

In 2024, Holosun began a collaboration with Ronin Tactics, a popular tactical training company headed by Tu Lam. So far, Holosun has modified three of its existing products for the Ronin series: the EPS Carry, 507 Comp, and AEMS Max.
 

Features

Each Ronin series optic has a few upgrades not available on the standard Holosun product. In the case of the Ronin AEMS Max, the glass size is tripled. It is the largest objective lens of any Holosun optic.
 

The reticle is Holosun’s MRS (Multi-Reticle System) that allows you to use either a 32-MOA ring, a 2-MOA dot, or a combination of both. The reticle is available in green or red. It also has solar backup capabilities and shake-awake technology.
 

Because of the increase in the size, the footprint is different than on the original AEMS, so those mounts won’t work. Not to worry – the AEMS Max comes with a lower third co-witness Picatinny mount that is lockable.

Carried over from the standard AEMS are the clear flip-down lens covers and 50,000-hour run time with CR2023 battery. Finally, the the Ronin Tactics logo is engraved on the housing, and it comes with an upgraded Pelican-style storage case.

Impressions

I loved shooting with this optic. When you first see it, it looks a giant brick on your rifle. Then when you get behind it, you see the point: there is just such a big field of view. It makes shooting easier and tracking targets a breeze, so you’ll never want to go back to a smaller optic.
 

It’s also not as heavy as it looks. It is lighter than an Eotech, so the weight and balance of your rifle doesn’t change much. The thin side walls make the optic barely noticeable. It is like a heads-up display, yet you still get a fully enclosed sight that is not susceptible to debris getting into the emitter. If gunk does get on the lens covers, just flip them down to clear it immediately.
 

Shooting Position

The large field of view is not just a luxury but has tangible performance benefits. First, it makes unorthodox shooting positions much easier. If you have ever tried shooting from under a car or through a VTAC barricade, both legitimate fighting scenarios, you know that getting your head directly behind the sight is the only way to get a precise shot. It can be difficult to contort your body. 

The beauty of red dot sights is that they are forgiving. If you can see the dot, you can take the shot. Because the Ronin AEMS Max has a giant window, you don’t have to bend your head and neck as far. It makes a difference.
 

Night Vision

The second advantage of the Ronin AEMS Max is in the realm of night vision. Shooting through a red dot with a Night Optical Device is called passive aiming. Not all red dots perform equally, as window size and glass coatings make a big difference. Currently, the Eotech EXPS3 is recognized as the king of passive shooting, but I think the AEMS Max is the next contender. I compared an Eotech to the AEMS Max using a NOD in the below video:
 

Just like with unconventional shooting positions, the big window makes it easier for the operator to get their head behind the sight with NODs. Also, it appears Holosun has perfected its glass coatings to work well with night vision. In the past, I have found Holosun products were a bit cloudy under a PVS14, but the AEMS has set a new standard for clarity. 
 

Conclusion

I appreciate that Holosun doesn’t keep sitting on its laurels, which would be easy to do as one of the top optics brands today. Instead, the company keeps improving its lines by adding new and innovative products. The Ronin AEMS Max is a home run and a great addition to the marketplace.
