## Description

desertcart.com : Monstrum Ghost Red Dot Sight | with Absolute Co-Witness Riser Mount | with Shake Awake Illumination | Black : Sports & Outdoors

Review: Very nice red dot. - I found Monstrum scopes to be a great deal with quality glass and adjustability. Was looking cor a cheaper red dot so decided to try this one out. It was a good choice. Adjusts great. The brightness setting is hard to turn but hopefully it will wear in some.
Review: Red Dot Magnifier - Game Changer for My Optics Setup - I recently added this red dot magnifier to my optics setup, and I am beyond impressed! This magnifier has significantly improved my accuracy and target acquisition, especially at longer distances. What I love: Crystal Clear Optics: The image through the magnifier is sharp and clear, even at higher magnifications. It does an excellent job of maintaining the quality of the red dot sight and enhancing the overall clarity of my target. Quick Adjustment: The flip-to-side mechanism is smooth and easy to operate. I can quickly transition from a non-magnified view to a magnified one with just a flip, and the adjustment is simple enough that I can do it without looking away from the target. Sturdy Build: The build quality is solid. The magnifier feels very durable, and I haven’t had any issues with it losing zero or becoming loose after several range sessions. Versatile: Whether I’m shooting at short or medium-range targets, this magnifier gives me the flexibility to quickly adapt to different situations. It pairs well with my red dot sight, providing better precision without the need for multiple optics. Easy to Mount: The mount is very secure, and I had no trouble installing it onto my rifle. The adjustments are simple, and it holds its position even after heavy use.

### ⭐⭐⭐⭐⭐ Monstrum Ghost...a nice red dot option for Katrina guns!
*by D***. on January 31, 2024*

I was looking for a standardized, cheaper red dots for some Katina guns. I say standardized as I'm not a gun collector. Everything I use should be fungible in an emergency aka standardized. Gun fondling collectors will have everything different and love variety. But in an emergency, you want standardization when it comes to each class of weapon. I tried the low-end Sig Romeo for $82 and Monstrum Ghost for $70. The Sig just could not compare to the Monstrum Ghost red dot. Even if the Sig was $40 I would not like it. Really, I like Aimpoints and ACOGs...but they are not disposable, so they are not doable for Katrina guns. I was really impressed with the Monstrum sight. It came with an extra battery, the dust caps worked fine, the battery is a standard wafer CR2032, compared to the oddball Sig battery. I could not get the flimsy Sig dust caps to lock. The dealbreaker with the Sig was I could not get a usable red dot until near midway on the adjustment dial. The Monstrum gives me usable red dots right from the beginning. And there is no need for the high # adjustment with the Monstrum, they are way too bright. Also, the Monstrum has a claimed 50,000 hour battery life. Fit and finish is very good with the Monstrum, really, I'd say it is excellent. I bought a number of these red dot sights and am very happy with the Monstrum Ghost. BTW, if you don't know what a Katrina gun is, check out what happened to gun owners in Katrina. And they never got their guns back. Time will tell how the Monstum holds up. But it is inexpensive enough to stock a number of them as backups.
