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.
Illumination Adjustments
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.
Variable Power Adjustments
To change magnifications, turn the magnification ring to the desired level.
The patented Vortex MagView
system will provide a low light
reference for magnification level.
