Product Description
Vortex Viper PST 5-25X50 SFP MOA Ebr4
The Vortex Viper PST 5-25X50 SFP MOA Ebr4 is an updated favorite that gives shooters an unfair advantage in every scenario, from fast-action close quarters to precise long-range shots. This high-performance riflescope is engineered to stay on target when it matters most, delivering dependable performance, clear optics, and durable construction that professionals rely on for years of accurate shooting.
At the heart of this scope is the EBR-4 reticle, a hash-marked rangefinding and holdover system that supports MOA or MRAD subtensions for precise corrections. The reticle is designed as a Second Focal Plane (SFP) optic, so the size of the aiming points remains constant as you zoom from 5x to 25x, ensuring your hold points stay intuitive and consistent across magnifications. The illuminated reticle adds another layer of versatility for low-light conditions, offering ten brightness levels plus a dedicated off position for rapid reversion to your preferred light setting. With these features, you can estimate range, dial windage, and compensate for drift without slewing your focus away from the target.
Optical performance is elevated by XD lens elements and XR fully multi-coated optics. The Extra Low Dispersion (XD) glass sharpens detail and fidelity, producing crisp edges and accurate color rendition that helps you pick up hints of movement and contrast at distance. The XR coatings maximize light transmission across all air-to-glass surfaces, reducing glare and maximizing brightness while preserving contrast. The result is a bright, high-contrast sight picture from first light through low-light moments, with edge-to-edge clarity that supports precise aiming and quicker target acquisition in dynamic situations.
Construction and reliability are the cornerstone of this riflescope. A robust 30 mm tube and a one-piece design deliver superior mechanical strength and broader, more repeatable adjustment travel compared with smaller tubes. The entire assembly is crafted from aircraft-grade aluminum, ensuring stiffness and resilience under recoil. The waterproof and fogproof design uses O-ring seals and argon gas purging to prevent moisture ingress and internal fogging in extreme temperatures and varying humidity. A hard anodized matte finish reduces glare and helps you blend into the surroundings, while ArmorTek adds an additional outer-layer protection against scratches, oil, and dirt—so you can rely on the glass and coatings staying clear through rough handling and field use.
Inside, precision engineering equips you for rigorous field conditions. The RZR Zero Stop feature prevents dialing the elevation turret below your established zero, guaranteeing you can always return to your starting point with confidence. The Precision Force Spring System and Precision Glide Erector System use premium components to deliver repeatable, smooth adjustments and reliable zoom behavior even when the environment is harsh or the action is rapid. A Radius Bar provides a clear, tactile reference for turret rotations, while the Fast Focus Eyepiece enables quick reticle focus so you can lock onto targets faster in changing light. The combination of tactical-style turrets and MOA-based subtensions ensures you have reliable, intuitive control over elevation and windage without guesswork, making this riflescope a versatile tool for both competition and practical hunting scenarios.
Beyond raw optics and rugged construction, this scope is designed for practical, field-ready use. The illumination dial is cleanly integrated into the side focus adjustment knob for quick access, so you can tweak reticle brightness without shifting your grip or losing sight alignment. This thoughtful cockpit layout supports rapid adaptations to lighting conditions, enabling a seamless transition between bright days and dim surroundings. The glass-etched reticle sits securely between two layers of glass, delivering durability and long-term reliability even in demanding environments. All these features come together to create a riflescope that is as dependable at dawn as it is at dusk, with the versatility to handle a wide range of calibers, optics preferences, and shooting disciplines.
