RIFLESCOPE

AinTenAnce

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.

Cleaning

• 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.

All components of the Vortex Viper PST riflescopes are permanently
lubricated, so no additional lubricant should be applied.

Lubrication

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.

Note: Other than to remove the turret caps, do not attempt to
disassemble any components of the riflescope. Disassembling of riflescope
may void warranty.

If possible, avoid exposing your Vortex riflescope to direct sunlight or any
very hot location for long periods of time.

Storage

roubleShooTing

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.

There are many issues that can cause poor bullet grouping.

Grouping Problems

• 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.
