Most Helpful Positive Review Awesome Magnifier
This was light, compact, bright, and my 1 moa dot was sharp. The eye relief was far better than others I tried. I paired this with my EOTECH xps2 and a PA QD flip mount. I was extremely happy - plenty of rail space to include my buis. Solid locking mount and no wobble.
Most Helpful Negative Review Without good mount worthless
Magnifier looks good. .. but needs Primary Arms mount. The swing away mount is WAY too high (like International Space Station High) given the eye relief and the bolt on rails for 30 carbine and Mini 14/30 (the rifles I'm using this on). Much better is the Vortex VMX-3T magnifier, that has an integr...

Unacceptable field of view

by petok, Verified Owner from GA, United States Written on March 4, 2020
I purchased this magnifier having used Primary Arms optics in the past without any issues, but this one didn't cut it. When you adjust the field of view to center your red dot the top of the field of view gets cut off and the image is no longer a perfect circle. This is not part of the red dot sight blocking the view because the chopped portion is still present when you look through the magnifier without anything in front of it. I contacted Primary Arms and told them my problem and we checked all potential variables (mount, height, allotment, etc.) before sending it to them to inspect and replace. They sent me a new one with a different serial number and it did the exact same thing. This was unfortunate because the price is great and the glass is clear, but having the image chopped at the top is unacceptable. I will be returning the magnifier and trying a different brand.
Pros:
  • cost
  • Sturdy
Cons:
  • field of view
Would recommend: No

Old Nam Vet

by Old Nam Vet, from AL, United States Written on April 30, 2018
LOOK no further than this Primary Arms Long Eye Relief Magnifier in 3x. Easily adjust vertical and horizontal to fit the glass on the combined red dot. Mated this to a American Defense Flip Mount in Absolute on an 8 inch SBR 300BO. Sight picture is sharp and no edges. The best feature overall is the LONG eye relief vs. the typical competition models. I can almost keep my same cheek weld on the stock vs. moving my face way up to find a proper sight picture. Good job PA and super shipping from OpticsPlanet.
Pros:
  • Almost Perfect Eye Relief
Cons:
  • Perhaps outside metal skin could have been made rougher for ease of movement?
Best Used for:
  • medium range shooting
Would recommend: Yes

Nice magnifier

by Alex Ivanov, from WA, United States Written on March 19, 2018
This is my first magnifier so I have nothing to compare to. Anyway it's easy to install and works well. Picture is clear and bright. Don't forget to follow all steps from installation manual precisely.
