The Viper PST Gen II 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.

XD™ Lens Elements Extra-low dispersion (XD) glass increases
resolution and color fidelity, resulting in crisp, sharp images.
XR™ Fully Multi-Coated Proprietary coatings increase light
transmission with multiple anti-reflective coatings on all air-to-glass
First Focal Plane Reticle Scale of reticle remains in
proportion to the zoomed image. Constant subtensions allow accurate holdover
and ranging at all magnifications.
Glass-Etched Reticle Allows for intricate reticle design.
Protected between two layers of glass for optimum durability and reliability.
Illuminated Reticle Provides precise aiming under low-light
Tube Size 30 mm diameter provides maximized internal
adjustment and strength.
Single-Piece Tube Maximizes alignment for improved accuracy
and optimum visual performance, as well as ensures strength and waterproofness.
Aircraft-Grade Aluminum Constructed from a solid block of
aircraft-grade aluminum for strength and rigidity.
Waterproof O-ring seals prevent moisture, dust and debris
from penetrating for reliable performance in all environments.
Fogproof Argon gas purging prevents internal fogging over a
wide range of temperatures.
Shockproof Rugged construction withstands recoil and impact.
Hard Anodized Finish Highly durable hard-coat anodization provides
a low-glare matte surface and helps camouflage the shooter's position.
ArmorTek ® Ultra-hard, scratch-resistant coating protects
exterior lenses from scratches, oil and dirt.
Tactical-Style Turrets Exposed turrets provide fast,
accurate and easily read elevation and windage adjustments.
INTERNAL MECHANISM DESIGN FEATURES
RZR™ Zero Stop Rapid Zero Return (RZR) feature stops the
turret from dialing below sight in range using rugged steel components.
Internal mechanisms stay free of sand, dirt, dust, moisture and other foreign
materials - even when setting the zero-stop position.
Precision-Force Spring System Uses premium components in the
erector-spring system to ensure maximum repeatability and ease of adjustment.
Precision-Glide Erector System This system ensures the
components in the zoom lens mechanism glide smoothly and cleanly through all
Radius Bar Fiber optic turret rotation indicator provides a
highly visible and tactile point of reference for turret rotations.
Fast Focus Eyepiece Allows quick and easy reticle focusing.
Built-In Accuracy Features Matching (MRAD or MOA) turrets
and reticles facilitate fast and accurate shooting at extended ranges. The
patented fiber optic Radius Bar visually assists tracking turret rotations.
Hash-marked reticle using MOA or MRAD-based subtension lines
and floating wind hold dots for ranging, holdover, and windage corrections.
