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

Great inexpensive adjustable scope mounts, work great for adding moa!!!For the price these are excellent quality. Compare to other that cost 5 times as much these seem equal in quality.

Perfect for mounting a larger scope as low as possible on a rifle. Also excellent for minimizing the need for major adjustments on your scope to zero in. Scope locks in place easily with a little blue thread locker. Excellent product.

nice scope rings for the price. these are low rings, so you might have to get a rail riser. But these are very well built.

These rings seem to be very sturdy. The only thing that seems to be a little on the cheap side is the screws are just a tad sloppy compared to more expensive rings. They aren't bad or loose, but they aren't as precise or tight as other scope rings I've installed. Shouldn't be an issue with lighter recoil rifles but on heavy recoil rifles I'd definitely put some lock tite on the threads. I put them on a .25 cal PCP with an Athlon Scope and these gave me the elevation I was needing since regular rings only gave me 15 minutes of elevation. Now I have 44 minutes which I'll probably never need that much. But, who knows, I may put this on a rifle that could use 40-50 minutes of angle. So why 4 stars? NO INSTRUCTIONS were in the box. If I hadn't been a fairly experienced shooter who's put on many sets of rings, I might have gotten frustrated. As it was it took me over an hour to put them on and get them adjusted to what I wanted to do. INSTRUCTIONS WOULD BE NICE!

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.

I needed the adjustably to move each ring indpendenlyi

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.

Yes! I really like these Monstrum adjustable mounts. They are durable, they fit my 8-34x56mm ffp scope like a glove. Price isn't bad either. The functionality of them is easy. 4 screws on each mount. Adjustability is easy. Thanks
