As light passes through and beyond the objective lens, the
resulting upside down image is sent to the internal lenses.
Known as erector lenses, these internal lenses return the im-
age to a right-side-up position. Finally, the ocular lens makes
a final enlargement of that image and sends it on to your eye.
Your Leupold scope was designed, manufactured, and tested
to ensure that, when properly mounted and sighted-in
on your firearm, you will enjoy exceptional performance.
A solid mount is critical to satisfactory performance of your
scope. If you have problems or questions, please contact
Leupold Product Service (see page 39).
