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 red 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

Perfect for what I needed and easy to install. Secures the scope well and stays secure on the picatinny rail all for a good price.

Works very well on my 7.62x39, no issues with it moving. Holding up very well and built tough.

So far so good. Pretty beefy and seems like it’ll hold up well. About 500 rounds on it and no issues. Well worth the money.

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.

Monstrum makes great products especially for the value. Fairly light and fits perfectly. Easy to install and holds optic security. Had to remove my picture for the review. I recon liberals don't like pew pews. Although that's what the product was for.

Optic fit perfectly and feels secure. Bolts onto rail and seems overbuilt and that is better. Installed in minutes and finish looks solid.
