Choosing an optic to ride atop your AR is often a compromise based on the intended use and desired range. A simple red dot will usually do the trick for home defense and other close-range applications because you’re not reaching out a long distance to hit your target. Conversely, longer-range applications such as hunting and hitting at greater distances require some magnification to see your target.
But suppose you want a CQB target finder and the ability to see at a decent distance without constantly mounting and remounting a different optic. In that case, you’ll need something with at least a little adjustability. So what do you do?
Enter the Holosun HM3X Magnifier. Adding a magnifier to a red dot can increase the range when needed but lets you go red-dot-only when you need to shoot closer in. A magnifier does exactly what its name implies: it magnifies the view of the target your red dot is planted on so you can see downrange better. But it’s not designed for ultra-long-range shooting, only medium distances, typically inside 100 yards. Beyond that, you’ll probably need to pull out a bigger optic to replace the red dot and magnifier combo.
A magnifier works by sitting right behind the red dot when in use but flips out of the way when not needed, such as when shooting closer targets. Need to see a bit farther out? Flip the magnifier up behind the red dot, and through the magic of optical science, your target looks closer.
The Holosun HM3X Magnifier is a versatile and reliable optic designed to amplify the capabilities of your red dot sight. Its robust construction, seamless integration, and swift operation make it a compelling choice for many shooters.
Solid as a Rock: Construction and Durability
One of the Holosun HM3X’s most striking features is its impressive build quality. The magnifier feels substantial, exuding a sense of durability that inspires confidence. The housing is constructed from high-quality materials, ensuring it can withstand the rigors of recoil and environmental challenges. This ruggedness is essential for any optic intended for use on a firearm, and the HM3X delivers in this regard.
Easy on the Eyes: Optical Clarity
While primarily a magnification device, the HM3X magnifier provides clear and distortion-free optics. The glass quality is commendable, offering a sharp image rendition that enhances target acquisition. Whether engaging close-range targets or extending your effective range, the HM3X consistently delivers a crisp sight picture.
Seamless Integration: Mounting and Compatibility
Mounting the Holosun HM3X to a Picatinny rail is straightforward. The included quick-detach mount securely locks the magnifier in place, providing stability and peace of mind. The low-profile design minimizes bulk and allows for a natural shooting posture.
One of the HM3X’s most significant advantages is its compatibility with a wide range of red dot sights. Whether you prefer a micro red dot or a larger model, the HM3X will likely seamlessly integrate into your setup. This versatility is a testament to Holosun’s commitment to providing solutions for diverse user preferences.
In my case, I threw my Mepro Tru Vision red dot on my trusty AR and lit up the range for a while, shooting from 25 yards out to over 100 yards with decent accuracy. My goal wasn’t to split hairs on the head of the paper target silhouette, just poking a decent group of holes from a comfortable distance with a relative amount of speed, like what might happen in the real world. A magnifier is not designed for ultra-distance shooting, so I kept the test realistic by plinking at moderate distances.
Quick and Convenient: Flip-to-Side Mechanism
The HM3X features a well-executed flip-to-side mechanism that allows for rapid transition between magnified and unmagnified modes. With a simple flip of the lever, the magnifier swings out of the way when not needed, providing an unobstructed view through the red dot. This design is particularly beneficial for dynamic shooting scenarios where speed is paramount.
The flip mechanism operates smoothly and securely, ensuring the magnifier remains in position when deployed, enhancing both usability and safety.
A Versatile Performer
The Holosun HM3X is a versatile optic suitable for various applications. Whether you’re a home defense enthusiast, a competitive shooter, or a recreational marksman, this magnifier can enhance your shooting experience. Its combination of durability, optical clarity, and user-friendly features makes it a compelling choice for those seeking to expand the capabilities of their red dot sight.
Two Significant Drawbacks
As versatile as the Holosun HM3X magnifier is—and it’s pretty darn versatile—there are two significant hiccups or considerations. First, it doesn’t work with every red dot out there. While it worked perfectly with my Meprolight dot, it didn’t work at all with Vortex Spitfire because it’s a prism optic, an incompatibility that would never have crossed my mind. I’m not an optics expert, so I can’t tell you from a purely scientific perspective what makes the two incompatible, but they are.
When I mounted the magnifier behind the Spitfire and flipped the magnifier down, the dot never focused. And I’m not talking about it being partially out of focus. It was bad, as in unusable. I’m not trying to diss Vortex. I have several of their red dots and other optics and have used them successfully for years. On their own, they are great. Their prism scopes just don’t seem to work with the Holosun HM3X Magnifier. Will they work with other magnifiers? I have no idea. If you’ve tried, I’d love to see your comments below.
Second, the Holosun HM3X Magnifier sits up a bit on the Picatinny rail, so if you pair it with a flush-mount red dot, you’ll need to add a spacer under the optic to raise the dot to the level of the magnifier lens. Otherwise, all you’ll see is the top of the red dot lens frame, not the dot itself. Once you get them aligned, the combo should work just fine.
Parting Shot
The Holosun HM3X Magnifier is a well-designed and executed product that delivers on its promises. Its solid construction, easy mounting, quick flip mechanism, and compatibility with various red dot sights make it a strong contender in the competitive magnifier market. While other options are available, the HM3X offers a compelling blend of performance and value that is hard to ignore. If you’re looking to enhance your red dot setup without breaking the bank, the Holosun HM3X is definitely worth considering.
