Best lowest rings for grooved reciever?

[philthygeezer]

I have a quality older rimfire rifle with an untapped grooved receiver. Which rings would fit nice and low and grip the rifle well?

Talley or Burris Zee rings, or even better Sako Optilock Quad rings!

Be aware there are at least two widths in use. 3/8" (0.375"), and 11 mm (0.433"). Make sure you get the right width rings for your gun. Some rosin in the groove slot and inside the rings, can help with slipping.
