Vortex Pro Series rings. Vertical split. Fit a 1" tube. I believe they are medium height, but they could be low? They came with a scope I bought from a member here so I don't have the original packaging or wrenches.
Please measure: Bottom of ring round hole to "top" of mount area.
Your picture looks like it might be 1/4", but hard to tell with the tape measure positioned below the ring.
