I am trying to figure out which size rail the Ruger 77/22 has -- is it 11 mm, 3/8", or ?? I have one that I am measuring at about 12.5 mm at the top -- but not sure if that is the proper measurement location.
All this consternation just to figure out what kind of rings will fit on it.
Hoping someone here knows off the top of their head...
