I have the same scope on a TC Compass 204 Ruger, originally this setup was on an AR-15. I ordered 1" Vortex Optics Hunter Weaver-Style Rings Matte Product #: 397323 from Midway USA. These left little distance from scope to flat top on the AR. On the 204 these rings leave about 1/2 inch from scope to barrel. Plenty high enough on the 204. The mediums should work depending on slope of barrel past the chamber.
