Cleaning
The fully waterproof and fogproof Vortex Viper PST riflescope requires
very little routine maintenance other than periodically cleaning the
exterior lenses. The exterior of the scope may be cleaned by wiping with a
soft, dry cloth.
When cleaning the lenses, be sure to use products, such as the Vortex Fog
Free cleaning products or Lens Pen, that are specifically designed for use
on coated optical lenses.
• Be sure to blow away any dust or grit on the lenses prior to wiping the
surfaces.
• Using your breath, or a very small amount of water or pure alcohol,
can help remove stubborn things like dried water spots.
Lubrication
All components of the Vortex Viper PST riflescopes are permanently
lubricated, so no additional lubricant should be applied.
Note: Other than to remove the turret caps, do not attempt to disassemble
any components of the riflescope. Disassembling of riflescope may void
warranty.
Storage
If possible, avoid exposing your Vortex riflescope to direct sunlight or any
very hot location for long periods of time.

Sighting-in Problems
Many times, problems thought to be with the scope are actually mount
problems. Be sure the mounts are tight to the rifle and the scope is secured
so it doesn’t twist or move in the rings. An insufficient windage or elevation
adjustment range may indicate problems with the base mount, base mount
holes drilled in the rifle’s receiver, or barrel/receiver alignment.
Check for Correct Base and Ring Alignment
1. Re-center the scope reticle (see Centering of the Reticle section on page
12).
2. Attach bore sighter, or remove bolt and visually boresight rifle.
3. Look through the scope. If the reticle appears way off center on the
boresighter image or when compared to the visually centered target when
looking through rifle’s bore, there may be a problem with the bases or
rings being used. Confirm that correct base and rings are being used—
and in the proper orientation.
Grouping Problems
There are many issues that can cause poor bullet grouping.
• Maintain a good shooting technique and use a solid rest.
• Check that all screws on rifle’s action are properly tightened.
• Be sure rifle barrel and action are clean and free of excessive oil or
copper fouling.
• Check that rings are correctly torqued per the manufacturer’s
instructions.
• Some rifles and ammunition don’t work well together—try different
ammunition and see if accuracy improves.
