RIFLESCO PE
All riflescope reticles can be termed either first focal plane (FFP) or
second focal plane (SFP), depending upon their internal location
within the riflescope. This model features the second focal plane
design.
S ECOND F OCAL P LANE R ETICLES
Second focal plane (SFP) reticles are located near the scope’s
eyepiece behind the image erecting and magnifying lenses. This
style of reticle does not visually change in size when you change
the magnification. The advantage of an SFP reticle is that it always
maintains the same appearance. Listed reticle subtensions used
for estimating range, holdover, and wind drift correction are only
accurate at one particular magnification.

DJUSTMENTS
The Viper HS LR riflescope uses a fast focus eyepiece designed to
quickly and easily adjust the focus on the riflescope’s reticle.
Reticle Focus
Once this adjustment is complete, it will not be necessary to re-focus
every time you use the riflescope. However, because your eyesight may
change over time, you should re-check this adjustment periodically.
1. Look through the riflescope
at a blank white wall or up at
the sky.
2. Turn the eyepiece focus knob
in or out until the reticle image
is as crisp as possible.
Note: Try to make this particular adjustment quickly, as the eye will
try to compensate for an out-of-focus reticle.
To adjust the reticle focus:
Warning
Looking directly at the sun through a riflescope, or any optical instrument,
can cause severe and permanent damage to your eyesight.
