    • Amazing glass quality, eye relief and FOV. Narrow eyebox EXTRA LARGE reticle
Style: 5x

Pros: >amazing glass clarity >very large Field Of View >large eyebox >Feels very solid, im sure this thing could take a hard hit or two just fine >i like the reticle >top rail for a red dot >Holds zero well after over 300 rounds Cons: >Very narrow eyebox >Larger than standard Reticle can make obscure small targets at range >.5 moa adjustment, with 5x magnification i'd prefer .25 moa but honestly small gripe Im genuinely so impressed at the clarity of the glass for this price. I can't think of an optic that is a better value in this price bracket, the glass clarity very nearly matches other Prism optics that around around 2.5-3 times the price. Also some of the best eye relief ive seen on a prism optic (even the $1000 name brand "battle proven" optics dont have this level of eye relief) I'm also quite impressed at the field of view this optic has, when you're looking through the scope the edges of the housing almost fades away and it's a much wider FOV than my other prism scopes The illumination is just fine, and it's daylight bright but honestly i rarely use illimitation on etched reticles but it's there if you want it. Before i get to the cons let me define two terms Eyebox: how much you are able to shift an optic left/right/up/down while still being able to see the full image Eye Relief: how much distance is required between the scope lens and your eyeball to get a full image My only gripes are that the reticle is quite large, compared to my other prism scopes on my PIRMARY fireARMS but imo it's not a deal breaker, and the eyebox is quite a bit more narrow. If you're buying this scope you're prob the type that shoots at a flat range and prob no more than 200meters. If that's your use case i'd say as long as you zero this optic for the very tip of the chevron at 100 meters as this can obscure smaller targets beyond that and this will produce tight groups(1.5-2moa) and that's all you can really ask for in a 5.56 rifle. Honestly if you just got this and a cheap micro red dot for the top rail you'd have a pretty fantastic budget equivalent to an ACOG stack. I'd just recommend you really practice presenting your rifle and learning the narrow eye box. As i said before even 1k prism scopes struggle with eye relief so a narrow eyebox is just a trade off but all you have to do is train yourself the muscle memory of getting a good image out of this scope. All in all i'm impressed at what monstrum is producing at this price and it's convinced me to try out their LPVO line ... show more

    • Not a multi colored reticle
Style: 4x
First, let me say I'm a big fan of all things Monstrum. In my humble opinion they are, w/out question, the best quality for the $ & I have several different models. The only complaint I have about this one is that (unlike all the others) this reticle is only available in red. Every other Monsteum prism scope I own has both red & green on it. So much so that I just thought that was a universal feature across their entire line of optic but apparently I was wrong. Still a great optic tho, just wish it did what all their other ones do! ... show more

    • Good scope but could easily be great
Style: 6x
It’s not perfect but for the money, it’s really good. Pros - it is very solid and well built, larger than I expected, easy to turn up rectile bright if needed, installs very easily, and has a true 5” eye relief. Cons - the biggest one will keep me from buying again, it come with no lens covers. The only other thing would be its lens good but not as great as other higher priced scopes. All this said this is about a third of cost of all my other scopes. But if they don’t include lens covers preferably flip down type, this will be my last purchase from them. Side note they also make a tri-pod that’s half of leaders cost and so well made, and easy to use. It’s the only tri-pod for my from now on. ... show more

    • Poor eye relief 2.5 inches not 5+ as claimed
Style: 6x
The eye relief was a big selling point to try and mount it on a sub2000 but it's more like a 2.5 inch relief and I could not comfortably use this on 2 different carbines. I loved everything about it but the eye relief was horrible, especially when expecting 5+ inches. I had to return unfortunately, it was a very nice product, maybe mine was defective. ... show more

Style: 6x
does not auto shut off. extremely high mount, like chin weld. reticle is not scaled right for 55 grain. reticle is so huge you only need the tip of the chevron out to 300 even with a 11.5

    • 4x sight works as described
Style: 4x
It’s a little bulky and a little too high on the rifle but for the rest it works very well, the glass is very clear, no visible distortions, the illumination works pretty well although is limited to the red dot and to the horseshoe ring. I got it with a Black Friday rebate for just $72.00 so you can’t really beat it ... show more
