  • 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. ... show more

  • Nice build quality
Style: 3X-HM3X
Fits nicely and securely on my pew pew. Not too heavy and the build quality feels nice. It even includes a silicon eye cap cover for both ends of the optic. My only gripe is the eye relief, not the best but still decent for the price point. Would I buy again? Yes, if I was in a pinch and in need of a magnifier asap, it’s does what it’s advertised to do. I will be exploring other magnifiers for future pew pew builds. Solid 4/5 overall ... show more

  • Excellent quality
Style: 3X-HM3X
This 3x Magnifier is one of the better-rated online and, on inspection, it truly is excellent in its glass clarity, eye box and eye relief. The Flip-To-Side action is very positive with no wobble in either position. Well worth your consideration. I'm happy!
