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.

Excellent 3X Sight for the $$$
I am not sure if I am going to keep this sight but I have set it up on my latest AR for a close quarter 100 yard weapon. The pic on the right is the sight out of the box and the pic on the left is after I started to dial the sight in. At 100 yards I was able to keep a group no larger than the size of my hand. I also did run water over the sight under my sink and it is def water resistant. I never needed the illumination for bright daylight as the etched black was more than adequate. I read reviews of cracking glass etc so was a little skeptical about durability. I have put about 500 rounds through my M&P AR 15 Sport II and its still holding zero. I think my ammo was 556 62 grain green tip. Maybe better ammo would have resulted in a tighter group. I rotated from a resting supported to sitting upright to standing and still was able to stick within a group no larger than my hand. For that I give this sight a solid thumbs up and recommend it for a prosumer type sight. Well worth 110$. Update: I have fired well over a 1500 rounds from an M&P AR 15 Sport II and this sight has held zero out to 150 yards even from a free standing position. My set up is for close quarter shooting. I really like the etched circle dot in the glass in case you lose battery power to illuminate the circle. I rarely even use illumination on the sight except in very low light situations. Glass looks very clean. For the money I would but it again. I may buy one again and just keep in case the one Im using becomes damaged. I wanted to test and test before I update. So far it has held up to my particular needs. I feel confident aiming and relying on this sight. The only negative I could add is it didn't come with a storage cover but that doesn't warrant dropping it to 4 stars.

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.

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.
