Best 3x Magnifier. Don't Bother Looking Elsewhere
Style: 3X-HM3X
So I have been looking to get a magnifier for a while and finally dove into the world of them. I tried a few out at a store and ended up ordering some super budget ones, but quickly realized their mounting solutions were not that good, and ended up with this Holosun HM3x...and honestly, this is the best one in pretty much most categories outside size and weight. But also due to its longer length, and mount being at the very front of the optic, your head is able to sit farther back on your stock when aiming, which to me, is much more comfortable. This is along with its 2.75 inches eye relief, which is one of the highest on the market, giving it a more forgiving eye box. The mount itself is study with a QD system to moving the magnifier between your applications is quick and easy. The hinge is similarly sturdy, and also easy to use as it is just a simple hinge with no buttons, but has no wobble or movement outside the positions it is meant to be in. The optic is very clear too, as your are able to adjust the diopter to focus the image, along with the adjustment not causing any noticeable changes to the eye relief, this thing has all the features magnifiers 2 or 3 times more expensive have. Centering adjustment is also very precise, with a smooth adjustment knobs, and does not lose zero. Magnifiers are magnifiers, they do not do much but magnify an image. I really do not see the difference between this and a EOTech G33 or G43, I have looked through a friend's. At the price, you are getting everything you need, at a very good quality. Best value for EVERYONE, from someone who wants to start, to those who want this on their main applications.

A well made magnifier I can recommend
Style: 3X-HM3X
Overview: This is a magnifier for use behind a red dot optic and I suspect a holographic type as well but I didn’t have one available Intended usage and suitability to task: I wanted a magnifier for use behind a trijicon MRO optic. I find that target precision is difficult with my aging eyes beyond 100 yards. The magnifier had to be at least 3x , have a good mount included and be weatherproof. This was not to be in place all the time so a quick release mount would be preferable. Glass clarity was important as it was the main reason for getting one. Eye relief had to be around 3 inches for my setup Function/appearance/ operation : The unit seems well made. It’s about average in weight compared to the others I had seen ( vortex, primary arms ) the mount was usable and flips to the right which I prefer. Several hard wiggles did not flip it which is nice as I don’t want it flopping around. The glass was clear and I did not notice any odd color casting. I was able to adjust the focus ring easily with glasses and with them off so the range of adjustment was good for my eyes. The magnifier set up well behind my red dot and I did not have to do any adjustments with the vertical or horizontal adjustment. The one drawback with it is when the red dot and magnifier are in place there is no room to mount it if you wish to keep all in the receiver and have a rear backup sight. It was not an issue in my case as I use offset back up sights so it was not an issue. Overall I believe the price was reasonable and it was well made and suitable for its intended usage and if your use / need is similar to mine I can recommend this unit.

Easily the best magnifier for the money
Style: 3X-HM3X
first I’ll preface this by saying my preferred setup is red dot with a magnifier behind it. I have both the Eotech G23 and the G33. One of them is behind and aimpoint micro while the other is behind an eotech exps3. On another rifle I’ve been using it has the MRO. I have a very slight astigmatism, it’s completely fine when using the red dot alone however, behind a magnifier it can definitely present some problems. With the MRO both the G23 and G33 magnifiers interacted with the dot terribly. Not only was it that typical smudge that you would see, one of them (G23) would smudge so bad there would almost be two dots visible in the glass. I’ve heard from a small handful of people that the holosun was eliminating the astigmatism problem. Now, while I know that simply shouldn’t be able to work like that I decided to give it a try for myself. To my surprise the 2moa dot in my MRO is crystal clear with the holosun, no smudge, no comet, nothing, it’s a perfect dot. I can’t explain to much as to why this is working like this but I’ll take it. For $200 it’s crystal clear glass, the body feels solid and the dot is actually a dot. The flip to side isn’t the best but it’ll do just fine. I’d definitely recommend this magnifier

incredibly impressed
Style: 3X-HM3X
For an under $1000 optic, I'm very impressed. It is fully functional and pairs well with mid level red dot's that themselves have good quality glass and reticule. The sight picture is great, no diffraction or color splitting detected, very sharp image. They eye relief is quite sufficient and in line with more expensive optics. I had no trouble aligning with my red dots however it should be noted that not all risers are made to spec or even advertise their actual saddle height so might have to fiddle. The diopter adjustment is very fine, a tad stiff but thats good. The qd flip mount can be adjusted to what ever level of stiffness you want so no complaints are valid there. There is a 'lock' button on the backside of the mount (if set to flip to the right) that inhibits setting it right up to BUS mount so I had to grind the nut on the BUS just a tad, easy. Range time shows much improvement over red dot alone, beats the crap out of iron sights. For pairing a 3x with a micro red-dot instead of LPVO I can't imaging a better setup for under $1000
