About this item

  • The Monstrum Marksman 1x Prism Scope is a prism scope optic with a true fixed 1x magnification
  • Offers similar functionality to 1x red dot sights for rapid short range target acquisition, but it uses a glass prism optical system with an illuminating circle dot reticle instead of the projected laser dots used in traditional red dot sights
  • Prism scope reticles are etched in glass, produces less distortion than red dots, and are easier for the eye to focus on, especially for shooters with astigmatism
  • Built atop the same platform as our 3x Marksman prism scope, it comes with an integrated 1.5 inch riser mount for true co-witnessing with your front sight and mounts to any standard picatinny mounting platform
  • The Marksman 1x prism scope is covered by Monstrum’s lifetime warranty

Bought the 1X for close work. The picture is sharp but instead of 1X it's more like a .5X Everything looks smaller and further away. Probably won't even mount it, will look for another brand prism sight.

Why did you pick this product vs others?:I chose this 1x prism because it has excellent optic properties which allows me to run it with both eyes open even though there are eye relief limitations.

The best dot sight I've ownedI have a bad astigmatism and can't use most dot sights but this one is very clear both on and off, great sight picture with the dot circle reticle both red and green illumination and off the black is very clear against most light backgrounds.The only negative for me is it is heavy but I guess that's where it's ruggedness comes from and I will definitely be getting another one.

Bought for a 10-22 for the diopiter adjustment for an astigmatism. Works excellent. Great eye relief.

This is my 4th Monstrum optic, and I'm as happy with this one as I have been with all the others. I went with a smaller prism due to astigmatism making my red dot look like an amoeba, plus I like the idea of the etched reticle always being available in case of battery failure. I'm also a fan of the circle dot reticle for CQB, so this optic checks almost all of my boxes. I'd love if this had a shake n wake capability, but that's my only real complaint. I'd also like it a bit smaller, but I won't complain because its relatively large size (for a micro prism) compared to some other manufacturers has its benefits as stated later.This is mounted on a CZ Scorpion carbine in a bullpup kit. So, it needs decent hight over bore. This mount does that perfectly. It has extremely generous eye relief for a prism, with a max of 6-6.5 inches.The eye box is fantastic, as is the field of view. The large size allows for a wonderfully large 30mm objective, so it's like looking through someone's front window. Absolutely vast. I love it.It zeroed quickly, with very few adjustments needed. The tabs on the turret caps worked well, and are a feature I've come to expect from higher priced optics. Something else I didn't know but gleefully discovered was the direction arrows for adjustment: I expected them on the turret itself like other optics. Instead, the direction arrows are inside the caps themselves, which I find fantastic. Instead of squinting in low range lighting to try and see tiny arrows in the turret, while also moving the rifle around to do so, I could leave the muzzle downrange and read the cap. The big, bright white direction arrows. Everyone should do this.So far, I've only run 150 rounds through it to get zeroed, but it held true. If its anything like my other Monstrum optics, I could run it over with a truck and it would hold zero.I recommend this optic whole heartedly.

I use this on a Ruger PC Charger. I have an astigmatism in both eyes, so a prism sight is nearly a must-have. I like the simple circle dot reticle over any other I've yet seen in a "micro" prism scope, and it suits this gun perfectly.The optics are surprisingly clear...I'd say they're about equal to most traditional scopes costing 2-3 times as much. Optimum eye relief is closer to 3.5-4 inches...6 is probably doable, but you'll lose a ton of field-of-view. I didn't do any testing on the adjustment tracking, or any of that; I simply mounted it and zeroed. Zeroing was pretty much trouble-free, and it has not shifted through 5 range outings with approx. 1000rds fired.I doubt this thing's up to anything much rougher than a trip to the range or for use on a "house gun", but that's all I need it for.Overall, it's been very well worth the price.
