Low Warne Maxima or Leupold QRW rings and Weaver bases are both low and rugged.
Low Leupold QRs are probably close to the Maximas and QRWs in height and they return to zero, but I have found that the levers are more fragile than I prefer.
I have a couple of rifles set up with 2 different scopes in QR mounts, Leupold 2-7x33s for regular hunting and 6x42s for first/last light situations.
