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.

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.

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.

Great glass quality
For a budget price point, This prismatic scope delivers! Great for sub 50 shooting, Elevation ,wind age Accurate! Solid feel and build quality, All metal construction, glass is clear, The parralax is adjustable I leave eye open and hit target with accuracy of that of a $500 plus scope set,green and red circle style bullseye to line up in lens.

A great little* optic for folks with astigmatism
I slapped this bad boy on my homebrew rifle and it works like a charm, the reticle can be as bright as you would like it, and lasts quite a while when accidentally left on while in storage. I put a few rounds through it, jostled it around some (threw it at a tree), and it stayed true as ever. If weight is of concern for your build, this optic may not be right for you, but I like a bit of heft on my rifle, so it is a welcome addition. If paired with a nice set of canted iron sights, you have a trustworthy and aesthetically pleasing gun.

I only regret I never tried this brand. They are extremely easy to use. With or without illumination, the aiming reticle is always visible.

I had my doubts but the 3x magnification and permanent reticle without need for batteries makes this thing very useful out on the semi-auto plinking range. It looks great on my Kriss Vector. The construction seems solid, but I'm not about to throw it down a flight of stairs to test it either. I enjoy this unit so much I intend on purchasing a second one for my Snowpeak M60B .35. The Monstrum Tactical P330-B is a keeper.

The black reticle illuminates so it is visible on a dark target (ie-black bear). It would be nice if the dot was smaller so it could be a little more precise when aiming at a regular dot target, but that is not that important for a short to medium range scope like this. I recommend this scope.

Its very heavy for its size but has a nice compact, low profile. Glass is okay considering it's half the price of most prism scopes

If you live in Canada, I would not recommend buying a scope from the US. You won't have any support and companies will not ship you parts or a replacement. For some odd reason, scopes cannot be shipped outside the US, unless you have a special license. I didn't know a scope could be dangerous. Weird! I bought the scope brand new in May. For an unknown reason, my battery is dead after using the scope only once. It was stored OFF and when I took it out this weekend, the battery was dead!?? I tried removing the cap, for the first time ever, in order to change the battery. Impossible! I tried with a coin, a screwdriver, and ended up messing up the cap. But it still won't budge! I finally managed to remove the cap with pliers. Needless to say it's not looking good anymore... Contacted the manufacturer, but they won't help me, because I live in Canada. They won't even send me a cap! Never buying a scope from the US again.
