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...

A magnifier that works

by Dan, Verified Owner from AZ, United States Written on October 20, 2025
I have an Aimpoint Duty RDS on my rifle and I just wanted to extend that visual out a little bit and this magnifier works perfectly. I love the quick release, and the adjustment tool built into the mount itself which really helps. I was able to get dialed in super quick and now I am zeroed further out than 50 meters. Covers keep the lenses clean and free of debris. I am very happy with this purchase.
Pros:
  • easy to use
  • Quick install & removal
Cons:
  • None
Best Used for:
  • rifle
Would recommend: Yes

Works great for my bad eyes

Works as intended

by Patrick, Verified Owner from SC, United States Written on September 19, 2025
It's a 3x magnifier and it works. Say what you want, feel how you want to feel about Holoson but it's solid, had zero issues with fitment on my rail. Works perfectly with my green dot (Holoson). If you want something built well and reliable that won't unnecessarily break the bank get the Holoson.
Pros:
  • Cost & availability
  • Color and design
  • Shipped and arrived fast
  • Fitment & function
Cons:
  • None

Best "bang for your buck"

by Charles Chapman, Verified Owner from NH, United States Written on September 16, 2025
I purchased 2 of these magnifiers, with lots of contemplation about spending much more money on an eotech or trijicon model. My concern was with adaptability and clarity, as well as toughness. I have an Eotech xps2 holographic sight and Trijicon MRO sight currently, but I wanted something versatile enough to do basically any sight I purchased. Im happy to report that this sight very easy works with either sight, is very clear, has a solid build that looks tough, and is compact enough to fit comfortably to any ar style setup. If you have an eotech or red dot without a magnifier, please please find a way to purchase one of these magnifiers. Not only does it magnify the sight really well, giving you much more capability, but it also seems to make the reticle more clear to get a better sight picture. The blurryness goes away and its very easy to fold the magnifier out of the way to go back to x1 zoom. Buy a few of these magnifiers instead of spending x3 the money on an expensive one. Once you have a few of these then you can try an upgrade and see if its significantly better but these will for sure get you through any situation at a fraction of the cost.
Pros:
  • Clear
  • Easy to use & operate
  • Cheap / good quality
Cons:
  • None
Best Used for:
  • red dot applications
Would recommend: Yes

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
