All Leupold riflescopes are made in the United States at their Oregon
facilities. Leupold makes them in all sizes and configurations, providing quality which always appeals to sensible consumers.
To use a riflescope with your shooting device, you'll need a mounting base and mounting rings in addition to the scope itself. You'll also need to settle on your preferred reticle type, as Leupold offers most of their scopes in many different choices of finish and reticle type.
With superior accuracy and reliability, the FX-I lineup of fixed-magnification units are ideal rimfire additions to popular rifles.
