This updated favorite hands an unfair advantage to shooters who seek to keep the upper hand in every situation from close quarters to long-range shots. The illumination dial is cleanly integrated into the side focus adjustment knob for easy access and streamlined performance. The glass-etched reticle offers shooters highly functional, intuitive, and detailed hold points, yet remains uncluttered for optimal viewing and features 10 intensity levels with off positions between each setting.

First Focal Plane Reticles

First focal plane (FFP) reticles are located near the windage and elevation turrets in front of the image-erecting and magnifying lenses. This style of reticle will visually grow and shrink as you change the magni cation. The main advantage of an FFP reticle is that the reticle subtensions used for ranging, holdovers, and wind drift corrections are consistent at all magnifications. The reticle is heavier at higher magnifications and finer at lower magnifications.

The Subtension Scale: 

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.

MOA Adjustments

A minute of angle will subtend 1.05 inches at a distance of 100 yards. Viper PST riflescopes with MOA adjustments use 1⁄4 minute clicks which subtend .26 inches at 100 yards / 7.3 mm at 100 meters, .52 inches at 200 yards / 14.6 mm at 200 meters, .78 inches at 300 yards / 21.8 at 300 meters, etc.

Windage and Elevation Adjustments

Vortex Viper PST riflescopes incorporate precision finger adjustable elevation and windage dials with audible clicks.

 To make adjustments:

1. Turn the adjustment knob in the appropriate direction: Up/Down or Left/Right as indicated by the arrows.

2. Following the directional arrows, turn the knobs in the direction you wish the bullet’s point-of-impact to go to.


MOA Adjustments

With each click of the Viper PST moving the point-of-impact 1/4 MOA, four clicks of the knob will move a bullet’s point-of-impact 1.05 inches at a 100 yard sight-in distance. At 100 meters, four clicks will more the point of impact 29.1 mm.

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.
