Monstrum Cyborg 4X Prism Scope | BDC Reticle

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.

Love it. Take it on and off and it stays true.

I was so very optimistic. I’ve had many great experiences with Monstrum scope rings and picatinny bases. Packaging was great. Product was solid and appeared brand new. The Monstrum Cyborg 4x is a feature-filled optic at a great price. Mounted it on an AR. Eye relief and FOV was great. But … there they were … bubbles … in the glass, in the center of the reticle! Rats!I returned the defective scope via Amazon Prime for a quick refund. My bad. This would have been a great time to test the Monstrum lifetime warranty. Instead, I ordered (and kept) two Monstrum Optimus 1x prism scopes. So far, so great! Read my review of those excellent optics.

I have always searched for bargains, and this is oneClear glassI like the reticleMount seems secureMagnification is in the sweet spot for meEye relief is goodEye box is forgiving, but not like a red dot, but red dots only work with batteries.The etched reticle on this is always thereillumination shows up with a white wall in the background, in full daylight(Texas daylight)I have a Primary Arms SLX 3x32mm Gen III I paid 3 times more than this one, and it's not 3 times betterLiked it so much, I bought a "used, like new'Yes I have 2., one on my !6'', one on my 18'

Nice compact set up for the price. I am still bouncing it between different AR caliber builds, and in all it works well and holds true!

This was my first prism sight after using many scope type sights over the year and I have to say this 4x Monstrum prism sight was a new and pleasurable experience. Disregard the reviews of those that have no idea as to how far away on the rail to mount the sight to eliminate “Scope Shadow” or not being able to quickly pick up the retinal. I prefer the green chevron over the red, making moa adjustments is quick and easy and using the bullet drop compensator (BDC) is easy to use once you have the sight zeroed for your preferred shooting distance all your required data is at your eye to hit targets further out or closer in. What’s not to like about this sight?I read reviews of whiners saying it’s too heavy, they can’t see through it, the eye box is too small, etc. these are kids that are trying to use a quality sight for paint ball shooting and not combat shooting and they haven’t a clue of the difference.Buy the sight, spend time in getting to know and understanding how the sight works, make your adjustments and enjoy one of the most affordable prism scopes available.

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.

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.
