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.

To adjust the reticle focus:

• Look through the riflescope at a
blank white wall or up at the sky.

• 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.

This Viper HS LR riflescope uses a fast focus eyepiece designed to
quickly and easily adjust the focus on the riflescope’s reticle.

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.

can cause severe and permanent damage to your eyesight.
