I am in the process of building a long-range lightweight mountain rifle and am looking to top it with a nice light-weight 4x14 (or so) scope with a minimum 30mm tube. I know the axiom of good glass is heavy glass, but I am trying to find the happy medium. I am looking for something under 20 ounces and am having a bit of dificulty narrowing the selections down. Any advice would be greatly appreciated. Thanks!
