VORTEX, PST-3151, VIPER PST Gen II 3-15x44 SFP EBR-4 MOA

The Viper PST Gen II brings you all the features of elite, top-tier tactical optics, with exceptional performance at a fraction of the cost. The 5x optical system delivers bright and crisp images across the zoom range with an impressive field of view for quicker target acquisition. Exposed turrets provide ample range of adjustment for dialing long-range shots, are available in MOA or MRAD and always match the reticle. After a day of dialing at extended ranges, the integrated, mechanical, RZR zero stop will bring you back to your exact zero every time with positive engagement.

OPTICAL FEATURES

• 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 surfaces.
• Second Focal Plane Reticle - Scale of reticle maintains the same ideally-sized appearance. Listed reticle subtensions used for estimating range, holdover and wind drift correction are accurate at the highest magnification.
• Glass-etched Reticle - Protected between two layers of glass for optimum durability and reliability.
• Illuminated Reticle - Provides precise aiming under low-light conditions.

CONSTRUCTION FEATURES

• Tube Size - 30mm diameter.
• 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 the riflescope 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 low-glare matte finish 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 - Zero Stop mechanism prevents the turret from dialing below sight-in range.
• Precision-Force Spring System - Uses premium components in the erector-spring system to ensure maximum repeatability and ease of adjustment.
• Precision-Glide Erector System - Uses premium components in the zoom lens mechanism to ensure smooth magnification changes under the harshest conditions
