A good balance between build quality and weight. - Zeiss Ultralight 1913 MS Rings

I put these on my .22LR competition rifle with a 50mm front objective optic. But the rings are sturdy enough that I would be confident putting them on any standard short--action bolt gun such as 6.5 CM or .308. For newer PRC cartridges, I might step up to a heavier, three-screw set of rings.

My build also does double duty as a hunting build so, I wanted something that had competition applications but also saved weight when I'm humping it around for game.
If you want rings for a pure competition application then I would note that the bubble is small. There are other ringed options with a larger bubble but for my use, this was perfect as it snags less than other options when hiking.
