## Description

Review: Wish I I had known about Monstrum before purchasing from Primary Arms - This 4x prism scope is better in every way than my $375 Primary Arms 3x Prism scope except in Size and Weight. It's definitely heavier, larger and bulkier than what I was expecting but when you look down the Lens you forget about all that with it's CRISP 4X magnification and that ∆ Chevron type retical, I forgot .....name^ . The red and green shake awake illuminations are easy button presses and at the highest settings aren't all blurry like I've found on my Primary Arms. The only thing I can't compare yet is if it keeps its zero which I hope I does as well as it's Primary Arms competitor. Highly recommend this scope and almost everything from MONSTRUM for that matter, they are that amazing company that puts out Quality Product and very affordable Prices.
Review: Great reticle, descent glass, great eye relief, great price. - This really surprised me. I'm switching to the Cyborg from a Vortex strike fire II with the Vortex 3x magnifier. I was very surprised. Mostly because I associate Monstrum with cheap Chinese trash but it seems like they are stepping up their game quite. It also looks like Chinese manufacturers are getting better. I was very impressed with the glass quality. It's not great but it is pretty good. I really like the BDC reticle and the illumination was cool as well. Really with the etched glass, there is a good chance I wont even use the even use the illumination. The overall build quality seems really good and it has held zero on my 5.56. The 4x magnification makes target acquisition a little slower than a red dot but it's not bad at all. Overall I wish I had bought this instead of spending 400+ on my Vortex setup. Very happy with the Cyborg so far.

### ⭐⭐⭐⭐ Great bang for buck provided the correct eye relief.
*by J***N on November 14, 2025*

I've purchased a few monstrum products and have been very happy with them, especially for their value. I wanted to try out prism scopes, and decided to give monstrum a try. This scope is pretty good in all honesty, the glass is great, the reticle is clear and the illumination the perfect brightness for lighting up the reticle clearly without scattering everywhere. The adjustment knobs are ok. I personally dont like the tool knob set up, but it is what it is, it has held zero up to 5.56 at least. The mount does its job. There are no lense covers/caps/killflashes to speak of, nor am I aware of any availible aftermarket. The biggest issue I have with this scope is the eye relief, it is pretty tight and unforgiving. I originally planned to toss this on a 10/22, but even after putting the scope as far back on the rail as possible, I could not get in the right place, which is a bummer because I otherwise would have loved it for that (it has since found an upper to call home, where the eye relief is much better) If you planned to put this on anything other than an AR, be aware.
