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

These rings are very sturdy and work great at adjusting the scope height. But also they work great for someone who needs to add elevation to their scope too, or even drop some elevation to correct a scope with not enough reticle travel for long range shooting. By loosening both mounts you can cant the scope up or down instead of ordering canted rails.

Great rings to use for scopes that cannot handle the MOA rails. It allowed me to use my Athlon bench rest scope on a 30MOA rail in my Ruger Precision Rimfire 22lr due to its limited 45MOA total elevation. I had to counter cant the scope mount. Just FYI, the max MOA rail your scope can handle is approximately half its total elevation (45/2=22.5MOA). Account for +/- 10MOA for other tolerances/imperfections in your rifle. Yes, our rifles can easily be off by that much. Eg. I tried counter canting my 30MOA rail with a 20MOA one piece scope ring mounted backwards to Net a 10MOA cant, and this allowed me to zero my Athlon. Even though I had approximately 22.5MOA of elevation adjustment, I almost bottomed out my scope. Which means I used around 21MOA to zero it despite just the 10MOA of total cant. With these adjustable rings, I was able to zero my rifle at 55yds while keeping the elevation turret near the center. There seems to be a little flex when pressing the scope down from its objective lens compared to a one piece mount but I don't foresee any issues since the recoil is fore and aft. For a 22lr or PCP/C02 airguns, the two screws that compress or sandwich the aluminum tang to tighten and adjust the heights will probably hold, but I would be more reserved on using this on high recoiling guns. Its just friction fit. Overall machining on this set seems pretty good from Monstrum, although I had an issue with their one piece inline rings. Great rings for its flexibility.

These ring helped with my .22 shooting at more then 250 yards. They helped me get more clicks out of my scope and still got to zero at 50 yards. Money well spent.

Nice scope rings. They don't fit the rail on my remington 11 87 slug barrel though. They only fit picitinny rails because of the two screws that hold the base to the rail.

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.

I have two other adjustable height scope mounts. One of them is an FX mount ($$$) the other is not nearly as good and the mounts have grooves to hold the adjustment but they do not move freely in the mount unless you carefully file the grooves out. The Monstrum mount was very close to the FX in quality and ease of use. The mounts are smooth in the mounts that allows for independent setting with no torque on the scope. Quick to install and easy to adjust. This one I will buy again if the need arises or if I replace the lesser mount.

Great concept, very functional, would be even better if there were hash marks to visually assess adjustments.

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.
