illuminaTion adjuSTmenTS
The Vortex Viper PST riflescopes use
a variable intensity reticle illumination
system to aid in low light performance.
To activate the illumination, rotate the
adjustment knob in either direction.
The illumination knob allows for 10
levels of brightness intensity; an off click
between each level allows the shooter
to turn the illumination off and return
to a favored intensity level with just one
click.

rZr Zero STop
Vortex Viper PST riflescopes incorporate the RZR Zero Stop feature.
After the rifle is sighted in, the RZR Zero Stop allows fast, sure
return to the original zero point when large multi-revolution elevation
corrections have been dialed into the riflescope.
Without a zero stop, the shooter must pay very careful attention
when dialing large corrections needing multiple revolutions of
the elevation knob. If the shooter loses track of the number of
revolutions, the original zero point may become lost. Because of the
RZR Zero Stop, the elevation knob on Vortex Viper PST scopes can
be quickly spun back to the original zero without having to carefully
count revolutions.
Once the RZR Zero Stop is set, the elevation knob will stop turning
at the original zero point when being returned from a temporary
elevation correction. Learn how to adjust the RZR Zero Stop in the
Boresighting and Range Sight-in sections on pages 12-15.
