Scope selection is an extremely import aspect of any rifle build. In this episode of our "Building A Backcountry Rifle" series we speak with Mark Boardman of Vortex Optics to learn what hunters should consider when selecting an optic to top their big game hunting rifle. We discuss the technical details of scopes, such as zoom ranges, objective sizes, exit pupil, and more — but in the end our purpose with this show is to explain those specifications so that we can make a more informed decision about what really matters: how a scope performs in the field.
