Most Helpful Positive Review Great 3x magnifier
Love it… Bright, clear optics w nice AR coatings. Very compact and very rugged. Magnifier swings out of the way & locks positively. Titanium housing is machined precisely & the mount is solid. Anyone buying this won’t be disappointed.
Most Helpful Negative Review Beware! Very Picky about the Picatinny Rail
I have not yet been the range with this magnifier, however once mounted it looks like it should work well. However I did encounter problems attempting to mount the optic. Issue #1 Attempting to mount it on a obscure produced Side Charging Upper, the optic mount would not clip onto the upper Pic Ra...

by JC, Verified Owner from SC, United States Written on December 25, 2024
Solid magnifier. QD mount is secure and the glass is very clear. Only downside is eye relief. Make sure you have enough rail space to mount it as far back as possible.
Pros:
  • solid
  • Clear
  • titanium
  • Heavy and durable
Cons:
  • Eye releif is a little short but nothing to worry about
Would recommend: Yes

Crystal clear vision

by DocAlamo, Verified Owner from MN, United States Written on December 2, 2024
I already had the Holosun 510 optic for my AR and wanted to pair it with a Holosun magnifier. Secure, quick-release mount, easy to adjust, very stable no matter how many rounds I shoot. I upgraded to the titanium housing. Love this combo!
Pros:
  • Excellent quality
  • well made
  • Sturdy
Cons:
  • None

Awesome product

by Styles, from MD, United States Written on August 4, 2024
You really can’t understand How much this piece of equipment helps your shooting until you use it. 3x doesn’t sound like a lot but wow, it is exactly what you need for your rifle to be spot on from 0-400meters.

Mount lost tension after one week of use

by Yeeper, Verified Owner from NM, United States Written on May 27, 2024
The magnifier is pretty good for the money. However, since the mount and magnifier are a package deal and most aftermarket magnifier mounts won’t work with this model, I’m reviewing them as one. The mount lost tension and flops all over if I’m moving quickly or moving the rifle a lot. Tried tightening it, nothing changed when torqued to spec. Not ideal. And since I paint all of my gear on my rifle, optics planet refused the return.
Pros:
  • Magnifier is decent for money
Cons:
  • Mount is junk
Best Used for:
  • Airsoft
  • Airsoft larp
Would recommend: No

Clear Glass, Simple Operation

by VoiciMossy, Verified Owner from OH, United States Written on January 6, 2024
I bought this to use with my Holosun HE510C which I was previously using a much cheaper UTG magnifier with. However, the HM3XT is lighter, crisper in the image and seems to have better light transmission. Also, the flip aside option is much simpler. To engage or disengage it you simply push or pull it in and out of your field of view. On the UTG you had to pull the magnifier back towards you to release it from its index whether to engage or disengage. On the SIG Juliet magnifier I have, you need to depress a button to unlock the magnifier so you can flip it in and out of view.

I have had no issues with the HMX3T flipping in and out of my way without these retention systems. The detent or whatever they use seems sufficient enough.

One tiny gripe is that I wish the magnifier sat just a tad higher. Even with the larger cowitness spacer, it barely clears my backup iron sight. I also cannot open the rear sight with the magnifier engaged. Also, I wish the magnifier had a larger eye relief. You really do have to lean in pretty hard to get a clear sight picture.

All in all, you're getting what you pay for. Usually I feel that with Holosun youre getting a screaming deal but with this, you're paying a premium for what is a very good product. It seems to be a simple, quality built optic and I'm glad I bought it.
