Reviews & Ratings for Primary Arms SLx 3x21mm Micro Magnifier Red Dot Sight — 22 reviews — Page 1

Great backup to the Primary Arms Slx 1x. Took a minute to zero to my slx but once it married looks great and sharp. When paired with Unity FAST FTC mount you can’t go wrong.

For the money it is hard to beat. Pair it with a primary arms 1x microprism and unity tactical mounts, and you’ve got a slick little outfit. This was actually my second purchase of this product for a friend. He liked mine so much he asked me to get him one too.

Clear optics and super light. I was able to find a reasonably priced flip-to-side mount that made this an affordable setup. Works great with the Primary Arms prism optics and regular prism sights as well.

With a built-in ranging reticle and clear glass, you can't beat this option. Easy to use and affordable too.

Excellent little 3x magnifier. Love the Pegasus version with the ranging hash marks. Has a smaller eye box than I'd like, but it's easy to adjust shooting position with a proper turkey neck cheek weld.

Couldn’t be happier with my purchase. Quality is great and I plan to use with the flip-to-side mount in front of a glx 1x micro prism optic

Solid magnifier and flip to side base. Magnifier range finder markings are clear and smooth. The flip to side base is solid. As sturdy as my eotech g45.
The magnifier sits behind Holosun Elite 65 MOA Circle 1/3 co- witness used the tallest shim to align the height.
The combination setup is perfect at 100yds really clear.
So good bought a second set.

This thing is nice, pairs well with primary arms SLX 1x micro prism. Cause the eye relief on the micro prism is similar a red dot, almost unlimited on how far you can be…

I purchased this magnifier to pair as a flip to the side option with a primary arms micro prism slx 1x. I have astigmatism and based on reviews I thought that the combination would work better than a red dot combo I used previously. The scope was amazing unfortunately, I was not able to get the magnifier to focus on the reticle of the scope at all following the manufacturer instructions and watching their videos on YouTube as well as others. I thought it was my astigmatism but then my sons couldn’t get it to either and they have 20/20 vision. Probably just a one off defective unit. I ended up returning it. Optics planet was great with their customer service and that was good. I have two other primary arms scopes and I wanted to love it but it didn’t work for me. I think the concept of 1x scope especially the amazing primary arms reticule and magnifier combo is good depending on the planned application but eye sight dependent.

This primary arms 3x micro magnifier seems like it will work. Strange thing is, I had to mount it in front of the primary arms 1x micro prism scope. When it was mounted behind the scope I could not see anything, all blurry. Moved it forward and it works as it should. I'm wondering if anyone else has encountered this strange phenomena. Overall, I'm going to use it and see what I see.
