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

Fantastic Budget Prism Scope
I absolutely love this scope and the price tag that comes with it. At $120 I was expecting it to be okay and somewhat clear, but I stand corrected. It is crystal clear and the reticle is nice and crisp when looking through it. It is actually on par to some of my high end precision scopes that cost way more than this does. The eye relief is a bit off as I had to move it fairly close to get a solid view, but still plenty of room to avoid scope eye. I love the illuminated reticle and although its not super efficient in the day, it creates enough of a contrast with the surroundings that its easy to pick up off a quick draw. Which is really saying something because in Florida, it is very hard to find an illuminated reticle that is actually functional in balls to the wall sunlight. I put this on an AR-50 chambered in .50 beowulf with the means to shoot relatively accurately at 25-50 yards, and boy was I absolutely stunned when the first time shooting it nailed a target at 25 yards with no adjustment at all. It handled the beefy round very well and held its zero longer than I could hold the firearm to my shoulder. My two very, very nit-picky complaints about this scope are the elevation and windage adjustments needing a coin or wide flathead to turn, and the actual weight of the scope. Although, I was able to pick up a brass case and adjust it without any issue, and since the rifle it is on is already pushing the 10 lb mark, it adds a nice counter weight towards the rear of the rifle. Overall, I am absolutely thrilled with this scope and recommend it to anyone looking for a budget midrange sight.

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.

Showed up today, going back tomorrow - cheap Chinese trash
BLUF: Don't buy this optic. Even $100 isn't worth it! Okay, so for the price, I wasn't expecting too much, and I got even less. I got this to put on a S&W Model 1854. 3x power, red and green reticle, I was good until it showed up. This optic IS NOT both red and green. It is only red. It has 10 brightness levels on the dial, but in real life, it has 2; super dim or kinda bright. When you turn the optic on, the circle on the reticle gets super blurry and, to me, seems to move. The dot does not stay a dot when it is turned on either. When I fired it up, on low, there are 3 dots. On bright, there's like 5. If you've ever turned on cursor trails for your mouse, that's what it looked like to me. Also, there is supposed to be a wrench to tighten the scope down. Well, you guessed it, no wrench. Now, with all that, if you are just looking for a 3x scope that you don't want it to be illuminated, this might work for you. It seemed secure on the Picatinny rail but I never even got to the range to test it out so I cannot tell you if it will loosen. There is no loctite on the screws for the adapter so you'd probably have to take the screws out and put it on yourself. I did try to get pictures of what I saw but the pictures were even worse so that would be useless.

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

Fast Target Acquisition perfect for a Kriss Vector and Plinkers
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.

Good Scope
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.

Heavy
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

Don't buy if you are Canadian
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.
