Turret Rotation

Vortex’s patented Radius Bar visually assists keeping track of turret
rotations and provides a quick visual reference that allows you to
confirm:

• Dial orientation is correct and has
not shifted as a result of accidental
contact.

• Dial orientation is at the zero point
when using the CRS feature (see page
10).

TIP: By watching the position of the
bar while making elevation adjustments,
you are able to quickly track full, half, and quarter rotations.

To get these benefits from the Radius Bar, the “0” mark on the turret
must be indexed with the zero reference line on turret post (see
Setting the CRS Stop and Indexing Elevation Knob on page 17).

Variable Power Adjustments

To change the magnification, turn the magnification ring to the desired
level. The MagView fiber optic magnification indicator provides a low
light reference for magnification level. A small tactile indent at the 5x
magnification setting allows you to quickly select 5x.

Illumination Adjustments

The Viper XBR scope features
a reticle illumination system
with variable levels of intensity
to aid in low light performance.

To activate the illumination,
rotate the adjustment dial
in either direction. This
illumination dial allows for 10
levels of brightness intensity; an off click between each level allows you
to turn the illumination off and return to a favored intensity level with
just one click.
