[Back Country Hunter]

I have a NS522 .22LR rifle that I would like to put low profile 30mm scope rings on. The rifle receiver is not drilled and tapped for bases, it only has the dovetail slots. I am having a difficult time finding low profile 30mm scope rings to fit a 3/8" or 11mm dovetail. Has anyone else run into this situation and found a solution? Thanks in advance for any assistance...
