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. Review: 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 ## Features - Next generation prism sight with 3x magnification and 30mm objective lens, for lightning fast target acquisition out to 300 yards - Features a glass prism optical system rather a refracting lens system like traditional scopes, allowing for better optical quality in a much smaller package. - Unlike red dots, the reticle is visible with or without illumination, for a clean sight picture regardless of lighting or environment. - Brand new single piece machined aluminum design, sturdier and more rigid than ever. 17 ounces in weight. - All Monstrum products are backed by a full lifetime warranty ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BW7MYSBN | | Best Sellers Rank | #185,048 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #394 in Rifle Scopes | | Brand | Monstrum | | Brand Name | Monstrum | | Color | Black | | Compatible Devices | Rifle | | Customer Reviews | 4.4 out of 5 stars 1,757 Reviews | | Eye Relief | 88.9 Millimeters | | Field Of View | 39.3 Feet | | Item Display Weight | 480 Grams | | Item Weight | 17 Ounces | | Magnification Maximum | 3 x | | Magnification Minimum | 3 x | | Manufacturer | Monstrum | | Manufacturer Part Number | P330B-DX1 | | Material | Aluminum,Glass | | Material Type | Aluminum,Glass | | Model Name | P330-B | | Mounting Type | Picatinny Mount | | Night vision | No | | Objective Lens Diameter | 30 Millimeters | | Product Style | DX1 Reticle | | Reticle Type | Circle Dot | | Sport | Hunting | | Sport Type | Hunting | | Style | DX1 Reticle | | UPC | 810088813603 | ## Product Details - **Brand:** Monstrum - **Color:** Black - **Compatible Devices:** Rifle - **Item Weight:** 17 Ounces - **Magnification Maximum:** 3 x - **Magnification Minimum:** 3 x - **Material:** Aluminum,Glass - **Objective Lens Diameter:** 30 Millimeters - **Sport:** Hunting - **Style:** DX1 Reticle ## Images ![Monstrum P330-B Marksman 3X Prism Scope - Image 1](https://m.media-amazon.com/images/I/41JaKs4zk3L.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Will it work for less than 20 yards?** A: It's three power so...at 20 yards I'd suggest open eye. **Q: Is this clear with a stigmatism** A: Yes! Big difference. Without long explanation this works basically like a standard scope as opposed to the reflecting light of a red dot. This also means you get an etched reticle that works fine without illumination.. still gives perfect black reticle with dead batteries. I have their older model and it solved my astigmatism problem with red dots. **Q: What kind of batteries dose it take?** A: Well uh, as it states on Amazon in the description....cr2032. **Q: What would be the best fit riser to get for this optic?** A: It would depend on the person and weapon it's being put on. I got a low Mount riser the my AR but that was for the way I shoot. Will have to chance it and hope the one you get works for you. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Top quality at a fair price! *by M***H on July 11, 2018* I love it! Its built well, solid, no flaws.

Only red No green but a very nice unit ### ⭐⭐⭐⭐ Good quality without breaking the bank. *by J***N on June 29, 2020* 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. ## Frequently Bought Together - Monstrum P330-B Marksman 3X Prism Scope - Monstrum Tactical Low Profile Picatinny Riser Mount with Quick Release, for Red Dots, Scopes, and Optics (0.5 inch H x 2.5 inch L) - Monstrum Lockdown Series Adjustable Height Picatinny Riser Mount with Quick Release | 2.5 inch --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/520004369-monstrum-p330-b-marksman-3x-prism-scope](https://www.desertcart.be/products/520004369-monstrum-p330-b-marksman-3x-prism-scope) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-07-08*
