MonstrumAdjustable Height, Adjustable MOA, Picatinny Scope Rings | 30 mm Diameter | Includes 1 inch Diameter Inserts

Installed these rings on an air rifle that was shooting very low and I had run out of upward adjustment . After a few attempts, I was able get on target and have plenty of upward elevation adjustment. I think these ring work well on air rifles since the range of MOA adjustment is so large and gives greater versatility than a fixed MOA base. I'm not sure how well they would work on anything more powerful than a .223, but they work well for me.

Best for the price. Don't over tighten. 1" and 30mm. Wish I could find them for 11mm rails. A must have for many airguns. Beats shimming your rings to compensate for barrel droop. The best solution for long range airgunning.

Excellent product, helps with moa

Solid buy, they do hold zero on my ar15 without any height raising, did raise height on 308 and it held zero on that as well. Too much branding on the rings make them ugly but just spray paint them black and you’ve got very solid rings

These mounts are super cool!! They allow you to keep the scope low to bore but still allow a MOA for longer range without having to purchase a new 10-20 MOA picatinny rail. I have had zero issues with these rings moving once torqued properly. Highly recommended.

If you have a problem with not having enough travel of the up elevation turret these scope mounts work perfect. I have them on both of my PCP air rifles.

Solid mount

While the Monstrum 30mm adjustable scope rings are of decent quality and perform well. They fall a little short of the higher-end name brands. What might help improve their performance by using a little thread locker to keep them secure? Make sure you use the thread locker on screws and attachments. These are decent value for the money.
