Monstrum P330-B Marksman 3X Prism Scope

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.

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

Right out of the box, you can tell it’s pretty high quality. Has good weight to it and feels very solid. Haven’t put it through a hard torture test yet though. Glass is very clear, no imperfections inside the lens that I can see. Good eye relief, too. The outdoor range was very bright out, which made the red/green illumination harder to see. There’s an “always on” black etching on the glass though, so you don’t lose anything with the dots turned off. Had it been overcast, I don’t think it would have been an issue. At the indoor range, it was vibrant, though. Zeroing in took some time. Out of the box, rounds were sailing a good 18” high and right off target at 100 yards (Ruger 556). Once I found zero, it stayed there for a couple hundred rounds. Seems to hold well. The only gripe I have so far is that after one range trip, there’s already a spot on the optic that is scuffed and the finish rubbed off. It’s on the ejection side, but I highly doubt the ejected rounds are hitting it. I’d have to set up a camera to tell for sure. Overall, there seems to be a lot of bang for a little buck with this optic. Works really well and aesthetically looks really nice on my AR.

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.

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.

I haven't used it at the range yet because of the shortage & all...but fit & finish is awesome! This thing looks so sick!...The reticle is clear, the focus ring is smooth, the glass is crystal clear, and the brightness levels are impressive (both red and green). The mount feels pretty solid too. A Youtuber named "704 Tactical" sold me on the sturdiness of the mount, he beat this thing up, it stayed on and held it's own. I'm REALLY hoping that it'll hold zero after a few hundred rounds, if it does, I'm getting a few more! As far as prism scopes I think this is the best bang for your buck. Yea there are other options like the Primary Arms 3x, but they cost twice as much...I hear NCstar makes a great prism scope too, but I like this one more. Hopefully it performs well, we'll see. I'll come back and update asap.

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 item

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

Absolutely great optic for the price I would definitely recommend !

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.

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.

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
