  • Great scope
Great scope for the price. Tons of adjustability. Very durable
Reviewed in the United States on July 21, 2025 by Jeremy Potter

  • Incredible for the price. Unbeatable
It’s hilarious how good this optic is. I have had zero issues with this optic on a .22lr. I’ve never had it go out of zero even after dropping it and throwing it around. The clarity is really good and the eyebox is about 2.5 inches even at 9x. You can’t beat it for the price, seriously. I would consider getting a good set of rings for it though! ... show more

  • Good quality for price point.
For a cheap scope you can’t go wrong. Mounted on my 22mag rifle. Only 4 stars, leaving room for potential better one in the future. May not be realistic.

  • Scope out THIS scope !
This scope was delivered safely and quickly - well padded and packaged and sealed. The scope was also in a plastic liner with silicone beads. A battery was already placed in the scope and there was an extra battery. This scope came with mounting rings and a hex wrench tool. A lens cleaning cloth was included as well as a Monstrum sticker and clear instruction. This scope is well suited for me and my needs taking reasonable ethical shots during hunting season. I would highly recommend this scope and have no reservations in offering that recommendation. ... show more

  • He got nice flatop M4 rifle with rail as a going away ...
This was the last weekI would get to do anything with my son as he is shipping out to boot. He got nice flatop M4 rifle with rail as a going away gift from his grandmother. So I went hunting for an inexpensive but appealing scope so he could really see what it was like. I seen fairly decent reviews about this product so we got it. It looked pretty cool, mounted rather easily, nicely boxed, very clean. I went and tried to unscrew the batter cover and it wouldn't budge. No big deal. I slowly pried it up with a dime after all, the instructions said to use the edge of a coin to remove it I seen the battery was already installed. Thought to my self, I have been here before, but that was another product. So, I rotated the intensity selector and I could see the green easily enough. Being partially Red/Green color blind, I was not too worried about not seeing a changing intensity red reticle. It may or may not have been working, but no matter, I prefer the green anyway. Funny though, the cap screwed back on very easily... Using my bore sight, I got the scope sighted in fairly quickly and headed out the the range the next day. My son couldn't hit the target as it was his first time using this scope and weapon. I seen it was a bit off after the first 2 magazines. Not a big deal. It takes time to get a scope just right. It seemed to be good enough for plinking. However, by the time we got through our 3rd magazine, I thought I was seeing things. The scope recital seemed tilted. I loosened and re-tightened it down in the rings. Shot twice more, and it seemed to be even more. Looked at it again, verified the scope itself didn't shift. Over the course of the next 10 shots, the recital rotated a full 90 degrees inside the scope. The ground was now clearly to the right. Understanding it was defective, I let my son try it again. He was able to get a good shot grouping because center stayed where it should, but watching the reticle rotate a bit after each shot was just too much. I think I will go and spend a bit more money one a quality scope and leave this one to be picked up by returns. A+ for Amazon Prime! ... show more

  • Will see soon.
Seems well built for the price. Nice clarity. Max zoom the sight picture isn't as great but not terrible. Eye relief is as stated. Between 3.5 and 4 inches. It will get put through the paces soon as its going on my 50 Baewulf. Will update after a few rounds. .....UPDATE... due to the price of ammo I dont shoot my 50 Beawulf much, but today was probably around the 40th round. Something inside came loose and i lost about 1/4th of my field of view. Im actually pretty bummed cause I actually liked this scope it was holding zero well. But considering the recoil of the rifle I shouldn't be suprised. Probably great for a 5.56 or 350 legend. I am not adjusting my 3 star review because I did gamble by putting it on that caliber. ... show more

  • Straight Banger
Another banger from Monstrum, these optics are clear as day and hold zero better than any other budget options ive dealt with, namely, UTG and Sightmark, i have swapped out all my optics for various Monstrum prism dots and scopes, even replaced the holosun i put on my POF .308 with a 3x prism scope and its held zero for close to 600 rounds, ... show more
