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

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.

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.

This is a great mount at a great value! Quality is not perfect but if you know how to mount a scope correctly this will give you zero problems.

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.
