Most Helpful Positive Review Primary arms absolute cowitness magnifier mount
Great mount. Sturdy and well built. Doesn't wiggle once it's in place. I use it on my eotech, and i like the absolute cowitness because with the eotech if you use the 1/3 cowitness you will part of the eotechs hood. Very happy with purchase
Most Helpful Negative Review Very poorly designed.
Do not purchase this mount. I love the optics that Primary Arms makes, but this mount is very poorly designed. After mounting my magnifier and heading to the range I noticed I kept having to move my eye closer and closer to see through the magnifier. I finally noticed the magnifier was no longer cen...

Does its job

by DHC, from WA, United States Written on March 13, 2022
It does it’s job just fine. This is my second one of these mounts. The first one stripped out after about 2 years from just normal use. Was happy enough with it to buy the same one again. Gets plenty tight in the magnifier.

Works okay, but there are cheaper options that work better.

by Dot6, Verified Owner from TX, United States Written on February 26, 2022
This unit works okay other than the spring is VERY stiff and pulling the optic back to unlock the pivot isn't very easy. I bought a NcStar that had a push-button release and quick detach mounting throw lever for only $15 and really like it better.
Pros:
  • works
Cons:
  • not easy to pivot, less expensive options out there
Would recommend: No

Good...for a while

by Dowzer, from MN, United States Written on January 15, 2019
I don’t use this flip mount often. After about 25-30 flips, the magnifier no longer lines up on the red dot centered. It is about. 1/2 down to the four o’clock position. It was somewhat centered when I got it but now it is moved about 1/2 way out of centered.
Pros:
  • cost
Cons:
  • Reliability
Would recommend: No

Optics Planet provided poor suggestion of package

by Cort Anderson, Verified Owner from WA, United States Written on April 7, 2018
Optics planet suggests that I purchase this in a package which included: Bushnell TRS-25, Primary Arms 3X Magnifier Gen III, and the Primary Arms flip to side mount.

This was a very poor suggestion. These parts do not match up concentrically: the view is skewed.

Each item seems fine (individually) for the price, but I wanted a set that works together...
Pros:
  • Inexpenseive
Cons:
  • Cheap
Would recommend: No

Does the job

by Joshua, from NC, United States Written on November 1, 2017
Works as designed. Takes a bit of getting used to when flipping, the amount of pull required to release is more than most people expect. That said, far better this than having the mount flip / flop on you when you don't intend and can least afford a distraction.
Would recommend: Yes

Decent mount, seems sturdy

by Mark, from OH, United States Written on March 16, 2017
I mounted this on my AR with the magnifier. At first it was hard to flip the magnifier in/out of position. But after working the mechanism a few times I got the hang of it. It's just a matter of getting used to it and then practicing with it. So far so good.
Would recommend: Yes
