RIFLESCOPE riflescope Manual
RIFLESCOPE The Vortex®Viper®PST Riflescope tm Specifically designed for the tactical, law enforcement and committed precision shooting communities, the Viper®PST series of riflescopes offer the highest levels of performance and reliability. With features such as matched turret/reticle subtensions, CRS zero stop mechanisms and precision ranging reticles, the Viper PSTs are ready for any situation.
RIFLESCOPE Reticle Options The Subtension Scale: MOA or MRAD The Focal Plane Depending on which version you have purchased, your Viper PST riflescope will feature adjustments and reticles scaled in MOAs or mrads. If you are unsure of which scale is used, reference the top of the adjustment turret. All riflescope reticles can be termed either first focal plane (FFP) or second focal plane (SFP), depending upon their internal location within the riflescope.
RIFLESCOPE Riflescope Adjustments Windage and Elevation Adjustments Reticle Focus Vortex Viper PST riflescopes incorporate precision finger adjustable elevation and windage dials with audible clicks. Vortex Viper PST riflescopes use a fast focus eyepiece designed to quickly and easily adjust the focus on the riflescope’s reticle. To adjust the reticle focus: Knob 1. Turn the adjustment knob in the appropriate direction: Up/Down or Left/Right as indicated by the arrows. 1.
RIFLESCOPE Image Focus and Parallax Correction Turret Rotation Select Viper PST riflescopes feature a side focus knob which should be used to fine-tune the image focus. When the image is sharply focused, parallax error will also be eliminated. Vortex Viper PST riflescopes incorporate Vortex’s patented Radius Bar to visually assist in keeping track of turret rotations. The radius Radius Bar bar provides a quick visual reference that allows the shooter Turret Cap to confirm: Using the Side Focus 1.
RIFLESCOPE Variable Power Adjustments Customizable Rotational Stop (CRS ) To change magnifications, turn the magnification ring to the desired level. The Vortex MagView system will provide a low light reference for magnification level. Vortex Viper PST riflescope elevation turrets incorporate the unique CRS rotation stop feature.
RIFLESCOPE Riflescope Mounting Rings and Bases To get the best performance from your Vortex Viper PST riflescope, proper mounting is essential. Although not difficult, the correct steps must be followed. If you are unsure of your abilities, it would be best to use the services of a qualified gunsmith. Mount an appropriate base and matching rings to your rifle according to the manufacturer’s instructions. The Vortex Viper PST riflescopes require 30 mm rings.
RIFLESCOPE Eye Relief and Reticle Alignment Bore Sighting After installing the bottom ring halves on the mounting base, place the riflescope on the bottom ring halves and loosely install the upper ring halves. Before tightening the scope ring screws, adjust for maximum eye relief to avoid injury from recoil: Initial bore sighting of the riflescope will save time and money at the range.
RIFLESCOPE Final Range Sight-In and CRS Stop Set Setting the CRS Stop and Indexing Elevation Knob After the riflescope has been bore-sighted, final sight-in and CRS stop set should be done at the range using the exact ammunition expected to be used while shooting. Sight in and zero the riflescope at the preferred distance. 100 yards is the most common zero distance, although a 200 yard zero may be preferred for long range applications.
RIFLESCOPE 3. After filling the center gap on the post with shims, replace the elevation cap. 4. Align the turret cap so the “0” mark on the cap matches up with the open slot of the turret shroud and the indicator line on the scope body. Again, be sure not to rotate the actual turret mechanism in the process. Align the elevation turret cap. 5. Re-tighten the retaining screws, but do not overtighten. Use of thumb and forefinger on the short end of the hex wrench will provide sufficient force.
RIFLESCOPE Maintenance Troubleshooting Cleaning Sighting-in Problems 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. 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.
