Great value, but...

by -

This guy provides usable clarity, color-correctness, and has less fish-eye than I was expecting, given the price point. It's a 3X prism, so eye relief is ok.

I bought it to use with my Unity Tactical Fast OMNI mount, but the ridges that run along the body of the magnifier are *just* too large to fit properly in the mount. It took a dremel to get the two to work together. Alas, the top adjustment (elevation) area would precludes the optic from being pushed fully into the bottom "locked" position of the mount, as it is upside-down when mounted, and the optic hits the top of your pic rail. Would recommend for a budget build as long as you're using a different mount.

Very happy

This was my first magnifier purchase and first primary arms optic. Fit and finish are great and the glass is clear. Definitely would recommend.

Pretty heffin nice

Its a phenomenal magnifier especially with the 1x prism. Just saw the 6x about to come out wish I would have waited but whatever these guys make high end products with low-end price so I'm a happy costumer

Best Magnifier

by -

This is by far the best magnifier I have found with respect to the eye relief. First time buying from primary arms, but I can tell you this product is high-quality and the mounting bracket for this is solid. This fit like a glove on my Smith and Wesson M&P 15 Sport II. I also had enough space to keep my rear hard sight. The set up is a true co witness and works great. Totally satisfied with this product and would recommend it to others.

Very surprised with this 3x!!

Received this today, wasted no time installing and torquing to specs and adjusting the diopter to get crystal clear sight picture. I was a little skeptical about this versus my other magnifier. One look thru it and that all changed pretty quickly. Glass is super clear, easier to mount, easy to adjust. (just be a little patient) Ordering another to replace my other magnifier and that will go on another build. Very pleased with this mag!! Well worth the money!! If you a little skeptical, don’t be. Just pick this up

Good magnifier

Real nice product, especially for the money.

Magnificent Magnifier

Easy set up even for a first timer. Nice Eye relief, clear glass, solid locking mount that is easy to manipulate with one hand. The unit looks great and functions accordingly. It is a little heavy but I like things slightly overbuilt. And the price, c’mon…..for this function/fit/ finish it has to be best in class. Another winner from P.A.!

Great glass.

This optic has great clarity and eye relief. I shed a bit of weight off my rifle replacing my old 3x prism magnifier and gaining a few inches of eye relief. I’m happy with the choice.

It magnifies.

Seems very well built. My first magnifier, and it... magnifies well. Had it out once already, really like it so far. Adds some heft to the top of your rifle, but worth it for the ability to reach more, in my opinion.

Nice magnifier!

Just got this for an early Christmas gift. It paired up really nicely with my SLX microprism w/ cyclops reticle. I was ready for a fight getting the diopters to cooperate, but it was super easy. Just tuned the prism diopter to my eye, as you usually would, and the tuned the magnifier diopter based off that; three minutes, no sweat. Glass quality is awesome, I highly recommend this product!
