HS-T
RIFLESCOPE
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.
Second Focal Plane Reticles
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
ideally-sized appearance when shooting with this SFP scope. Be aware
that the listed reticle subtensions used for estimating range, holdover,
and wind drift correction are only accurate at the highest magnification.

The Viper HS-T 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.

Variable Power Adjustments
To change the magnification,
turn the magnification ring to the
desired level. The Vortex fiber
optic magnification indicator will
provide a low light reference for
magnification level.
