Vortex Optics VIPER HS LR 6-24X50 RIFLESCOPE — First Focal Plane - Manual (Page 3)

HS LR
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 first focal plane design.
First Focal Plane Reticles
First focal plane (FFP) reticles are located near the windage and
elevation turrets in front of the image-erecting and magnifying lenses.
This style of reticle will visually grow and shrink as you change the
magnification. The main advantage of an FFP reticle is that the reticle
subtensions used for ranging, holdovers, and wind drift corrections
are consistent at all magnifications. The reticle is heavier at higher
magnifications and finer at lower magnifications.

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.
