Complete The Look

The Vortex Viper PST Gen2 3-15x44 SFP EBR-4 MOA Scope brings all the features of elite top-tier optics at a fraction of the cost. Featuring a 5x optical system that delivers bright and crisp images throughout the zoom range and an impressive field of view for fast target acquisition. The exposed turrets provide ample adjustment for dialing in long range shots. The integrated mechanical RZR zero stop that brings you reliably back to zero 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 Allows for intricate reticle design. Protected between two layers of glass for optimum durability and reliability.
      • Illuminated Reticle Provides precise aiming under low-light conditions

Construction Features:

      • 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 magnification ranges.

Convenience Features:

      • 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.
