I recommend the DNZ one piece mount for TC guns. and any good steel rings.I also recommend Nikon or Bushnell MZ scopes. I like what most consider very heavy loads and have wiped out a number of scopes with recoil including some of the brands other people recommend. I have shot some of my Bushnell and Nikon scopes for many years and never had a problem. The Bushnell Banner Dawn to dusk MZ scope and the two Nikon MZ scopes are my first choices for reliability.
