These are a good ring for the money. They are very solid. You must remember that the "Interlok" insert is reversible if you remove the center screw entirely. They are as high as most folks "high" rings and they only come in one height. They would be good on an AR15 flat top. I have their 11mm dovetail rings on an Anschutz 164 .22 and they are just right for that.
Pros: Good value.
Cons: Higher than a medium ring.
