Top quality at a fair price!
I love it! Its built well, solid, no flaws. It was heavier than I imagined, but its very sturdy and that's what I was looking for. The scope is crystal clear with a decent eye relief. The reticle is clear and the lights work perfectly, amd are plenty bright/dim enough for any occasion. On a Milspec AR the scope "co-witnesses" the A2 front post (which doesn't work like a red dot because of the magnification) so I purchased the 7 slot monstrum quick Detatch adjustable riser for about 18$ and that is perfect for this scope and puts it at a comfortable eye level on its lowest setting but still keeps the sight clear of the front post. I haven't had the chance to go to the range but I'm sure it will have no problems as the construction is solid and its not a "cheep/crappy" sight, this thing feels like quality, on par with the major (expensive) brands. My only complain is that you can't get a cover for the lenses, but you don't really need them. it also comes with batteries installed plus replacements, along with a lense cleaning cloth. Hope this info helps some potential buyers, I recommend this sight without a doubt! Top quality at a fair price, no corners cut.

10/10
Very nice scope. I had to do some serious work on getting it sighted in.... it was VERY HIGH AND VERY LEFT But after that no complaints. The bottom bolts did however back out and get loose after 60 or so shots so I would recommend some lock tight or 2 step epoxy on them. Great visibility, no glare no fog very crisp. Only red No green but a very nice unit

Nice scope for the price
Ordered this as a slightly magnified alternative to my red dot. Image is clear, reticle lighting is nice, it has held zero with no issues so far (a couple of trips to the range), and seems pretty well made. Depending on your application…I would also recommend ordering a riser for it. I did and it sits nicely on my rifle. The eye relief is pretty good as long as your application doesn’t kick super hard. So far so good! I’d definitely recommend this for smaller rifle applications.

Great quality product as always from Monstrum Tactical at a reasonable working mans price. Well built, made to last, easy to zero in and holds zero. I repeat, YES IT HOLDS ZERO and that's what's most important when choosing a scope. Clean, clear glass with brightness adjustment settings for Red and Green dots and just incase the reticle is etched into the glass making it still useable if your batteries should fail. Has a great focus adjustment knob to help you get a clean, clear, crisp view of your target. Looks great on my rifle and was shipped fast too. No worries buying from Monstrum Tactical as the have the best customer service around. I plan on buying another one soon when the wife isn't looking.

As others have said, eye releif
It looks good, has clear glass and the illuminated reticle is just fine in or outdoors for me. The biggest problem is the eye relief. I have a side mount on my AK47 and Magpul MOE furniture and either this has to be all the way at the back end of the mount which just looks wrong hanging over, or you have to rest your cheek on the top cover latch. I really wanted this to work because the setup looks great but the eye relief just makes it no good for my use. The AR guys may have better luck but I wouldn't bother on an AK. I was going to buy its brother the other P330 but that has the same eye relief so I guess I have to save real money and get something else. Shame, because in all other ways its a nice optic and a STEAL at the price.

TWO THUMBS UP
Love these, got em on all of my AR platforms. perfect for 25 yard shooting, provide clear sight pictures, love the lighted reticle. these work just as good as the expensive ones for a fraction of the cost. the newer models only have red lighted reticles the older ones had a choice between red and green, i prefer green but you gotta take what's available.

Great Value Circle Dot 3X Scope
Great circle dot 3x scope. Works lit or unlit (adjustable brightness too). Easy to zero and holds zero well. Is a bit heavy but overall a great value, especially at this price point.
