Excellent quality and robust set of rings. The upper mounting gives you so many options for lighting, level sensor etc

Great machining very heavy duty. Don’t think I’ll use the bubble unless I pick up a rangefinder.

I am using these on a .22 lr rifle. For my purpose they have proven to be solid performers for reasonable cost. The manufacturer quality is excellent especially for the very reasonable cost. T I see zero reason to select a much higher price product for what I am using them for. Would purchase again.The inserts seem to be made of a hard synthetic material which does not scratch or mar the scope finish.

Ordered them and they did not work for my application. I ordered a different set on 11 Feb and was told when I asked where they were, that I had to wait until 25 Feb for them to ship. Had to buy a different set locally so I could mount and use the new optic before my next competition.

Ok, these are pretty good. The rings themselves are very high quality. The diving board needs some work. The diving board (in my opinion) need some bosses or some other design element to keep it lined up correctly with the long axis of the rifle. The diving board has a lot of left-right play that needs to be engineered out of the design. Time will tell if that board is going to hold zero or shift.
