Good value - be sure of the torque pounds when tightening
Size: 1 inch diameter
Style Name: 2 inch Offset
This was very functionable and did great. It's a tough mount, looks good, and excellent value. I made a boo-boo of overtightening and stripped one of the threads....I should have checked the foot pounds for torque.....will do so the next time.

VALUE & QUALITY !
Size: 30 mm diameter
Style Name: 1 inch Offset
I am an avid target shooter and have over ten rifles that are scoped and of course that means a lot of scope mounts . Most of my scopes are mounted to picatinny rails .As a serious shooter I have been happy with both Leupold and Warne one piece scope mounts because of their quality construction and durability . I love Amazons great selection so when shopping for my newly ordered scope , I browsed and read the great reviews . I have bought several accessories from the Monstrum company and have been impressed with their quality ! When I read the excellent reviews on the Deadlock Pro Cantilever Scope Mount , I thought that I would give it a try . Amazon's delivery actually got the mount to me several days before I received the scope that had ordered a week before so I had a week to really study the value and installation functionality before installing the scope yesterday ! I was blown away by the sturdy design and quality ! It was light weight and the ring design was superior ,not to mention the finish ! Do yourself a favor and try one ! This will be my Go-To mount and the Value is amazing

Very slick design and has alot of securement. Very Easy to install. Just see the torque specs and install. Seems very well built and durable. Comes with 2 extra screws. The product itself is very lightweight for what it is.

Solid Mount for the Price – Better Than Expected
Size: 1 inch diameter
Style Name: 2 inch Offset
I picked up the Monstrum Deadlock Pro Cantilever Mount for my AR build after looking for something affordable but still reliable enough to handle moderate use. I honestly didn’t expect much given the price, but I’ve been pleasantly surprised so far. Right out of the box, the mount felt sturdy and well-machined. The finish was clean with no sharp edges or tool marks, and everything lined up as it should. Installation was simple—I mounted it to a standard Picatinny rail and torqued everything down to spec. The hardware felt solid, and I appreciated that the included screws didn’t strip or feel cheap. I mounted a scope and have taken it to the range a few times now. It held zero after a couple hundred rounds, which is more than I can say for a few other budget mounts I’ve tried in the past. I haven’t noticed any shifting or loosening after use, and it still feels locked in place. One small downside is that it’s a bit bulkier than I expected. Not necessarily heavy, but just a little more material than some of the sleeker, higher-end mounts. That said, it's purely a cosmetic thing—it doesn’t get in the way or affect function. Overall, for a budget-friendly mount, this exceeded my expectations. It does what it’s supposed to do, holds zero, and feels reliable for casual shooting. I wouldn't hesitate to use it on another build, especially if I'm trying to keep costs reasonable without sacrificing too much quality.

It works as well as an expensive alternative
Size: 30 mm diameter
Style Name: 2 inch Offset
I have several different Montrum scope mounts and have had very good experience with all of them. I used this mount for an LPVO and it does exactly what it is supposed to do. It fit the scope well and holds zero.

Good mount for the money
Size: 30 mm diameter
Style Name: 2 inch Offset
I ordered a few different scope mount. Two from monstrum and one from a nothing company. This mount was the nicest out of the three. The other monstrum mount had corrosion in the screw holes. I would say this could be hit or miss. I would say there's a possibility a number of these have this issue but this one was nice. Going to return the others.
