Expert Review

Great glass for a reasonable price

by Julia, Gear Expert from IL, United States Written on December 15, 2020
I've had this mounted for about a year now and really like it. Pairs well with a red dot for longer shots as well as for target identification for people with relatively poor vision like myself. Seems very durable, and I haven't had any issues with the glass not staying put in either the upright or down position- looks into place nicely, the eye relief is generous, and the glass is exceptionally clear.
Most Helpful Positive Review Eotech magnifier level of clear
this thing is so clear. bought it at my ffl dealer shop when I was picking up my aero a4 lower and saw this beauty for 199. I asked him if I could take a look at it and he told me he had just put it on display a half hour ago. I jumped all over it. it is slightly larger than an eotech magnifier but...

Most Helpful Negative Review Bad luck with mine.
Good eye relief and the clarity was fine for the price, until two large black flakes appeared on different strata of the internal lenses--enough to blur the view at the center. Not subjected to any severe recoil or rough handling, maybe 1k rounds of 5.56 from a bench before the issue became apparen...

AWESOME MAGNIFIER

by Jason Peterson, Verified Owner from VA, United States Written on June 21, 2025
I put this on my son's 300 blackout that I built for him since his passing and I tell you what... where has this been the whole time I've been shooting. I had a friend of mine with me and he said that he needs one for his rifle now as well. Highly recommend

Worth every dollar

by Dalton Wells, Verified Owner from SC, United States Written on June 9, 2025
For the money you can't go wrong with Holoson. Durability and performance is on point. It doesn't match up to a 1-8 lvpo but its not ment to. This is 100 yard in nail driving enhancer. Especially for 300 blk because really!? If you want a quality mono magnifier for a red dot this is it man.
Pros:
  • Durability, quality, eye relief
Cons:
  • None
Best Used for:
  • Enhancing a red dot

HS HM3X 3x Magnifier

by Paul Hinders, Verified Owner from MD, United States Written on April 29, 2025
Shipping was quick and product received was as listed though ive never had an issue with OpticsPlanet.

The product itself was easy to adjust and mount, the quick disconnect rail mount was easy to work with and makes managing this thing a breeze.

The eye relief is nice, set infront of the rear folding iron sight and still provides a good cheek weld when viewing

Aligns perfectly with my sig romeo 5 with no adaoter plate, glass is exceptional and provides easy flip to the side for going straight to the optic.

Horrible Glass

by MEH, Verified Owner from OR, United States Written on April 18, 2025
Out of focus and blurry. First and last one of these I will ever buy. Ripped almost $27 to return this junk. Spend your money on a 1-4 power small optic.
Pros:
  • mounts well
Cons:
  • None
Best Used for:
  • nothing - do not buy

Quality optic at great price point

by Lewis1911, Verified Owner from TX, United States Written on April 15, 2025
I am a bit of an optics snob and usual opt for the Eotech’s, triji’s and so on. I purchased the Holosun thermal out of shere curiosity, and ended up ordering the 3x magnifier to go with it. Although slightly longer than the EO, it’s also half the price, and so far provides the same performance as its higher-priced competitors. I could sing it for eye-relief, but to be fair, none of the magnifiers in class have great eye relief, so I have it running along side the rest. Not bad, Holosun make some solid optics, and the 3x mag is pretty solid
