Great scope ring.
These work exceptionally well for the price. They are a tad on the heavy side, but I used them on a light weight rifle. They are surfy, install easy, and are really stable. If needed I will buy more

Good product if limited for options
I’m giving these 5 stars because there’s really nothing wrong with them. They feel well made and sturdy, with great overall fit and finish. If you’ve invested in a scope that requires 34mm rings, you’re likely in a situation that might call for a more premium product, but these definitely hold up well. My only minor gripe is that the ring bolts and mounting bolts use the same Torx bit but have different head diameters. This can lead to some marring if you accidentally mix them up, so just be careful when installing. Overall, a solid choice for 34mm rings.

Well made mounts to ensure scope stability, alignment, and accuracy necessary for precise shooting
These are great scope rings - hubs was thrilled and I bought two sets. Nothing makes him happier during off-season that setting up for next season. Scope mounts are essential for securely attaching an optic to a rifle, ensuring the stability, alignment, and accuracy necessary for precise shooting. They bridge the gap between the firearm and the scope, allowing it to hold zero under recoil, manage eye relief, and provide necessary clearance from the barrel. These tighten securely and handle the scope weight and the transport jiggle. Very good product and easy installation. Be sure to order to fit your rail and scope. Well worth the money.

Good solid rings
Nice looking, solid mount and 6 screw rings make for a solid setup even with stiff recoil. Mounted on a 444 Marlin.

Seems okay so far so good.
I bought these because they were cheap. They seem to be working with my LPVO pretty good I got it on a 357 Magnum lever gun. Seems fine.

Quality build
I recently picked up the Monstrum Deadlock Series Scope Rings, and they’ve exceeded my expectations in both build quality and performance. The first thing I noticed was how solid and well-machined they feel — the 6061 aluminum construction with hardened steel hardware gives them a premium, durable feel right out of the box. Mounting them to my Picatinny rail was quick and straightforward thanks to the custom locking bolts, and once torqued down, they haven’t budged a millimeter, even after repeated sessions with a heavy-recoiling rifle. The design strikes a great balance between strength and weight; the strategically placed lightening cuts keep them from adding unnecessary bulk, yet they still provide a rock-solid hold on my scope. I’ve run them through long range days and rough field conditions, and they’ve held zero flawlessly. The anodized finish not only looks sharp but has resisted scratches and wear far better than I expected. Overall, these scope rings deliver the kind of reliability and stability you want when precision matters. If you’re looking for a lightweight yet rugged mounting solution that can handle serious recoil and still keep your scope perfectly aligned, the Monstrum Deadlock Series is a fantastic choice.
