Vortex Viper PST Gen II 5-25x50 EBR-4 MOA - Long-Range Precision

Overview

The Vortex Viper® PST™ Gen II 5-25x50 SFP EBR-4 MOA is designed for precision shooters, long-range hunters and professionals who demand reliability and optical clarity. Built around a high-definition optical system and an EBR-4 reticle in the second focal plane, it delivers a consistent image regardless of the chosen magnification — a benefit for shooters who prefer a stable reticle size from 5x to 25x.

Technical Specifications

• 5-25x magnification, 50 mm objective: versatility for medium and long-range shooting
• XD (Extra-Low Dispersion) optical system and XR multi-coating: edge-to-edge sharpness and markedly reduced chromatic aberration
• Illuminated EBR-4 MOA reticle, second focal plane (SFP): MOA subtensions for range estimation, hold-over and windage corrections, with 10 brightness levels and an off position between each setting
• Exposed turrets, graduated 1/4 MOA per click: precise adjustments, red fiber-optic markers on the dials for quick visual checks
• RZR™ Zero System: fast and reliable return to zero after multiple elevation revolutions, ideal for large corrections in the field
• Adjustment range of 35 MOA windage / 70 MOA elevation: sufficient margin for long-range shots
• 30 mm aircraft-grade aluminum tube, ArmorTek coating: durability and protection of the external lenses against scratches and weather
• O-ring sealed and argon purged: fogproof and shockproof construction
• 97 mm eye relief, field of view 6.4-1.4 m/100 m: sighting comfort and positioning flexibility
• Matte black finish, weight 907 g, length 368 mm: discretion and balance on the firearm

Use and Maintenance

Adjust the parallax using the side dial to obtain a sharp image according to shooting distance. Adjust the reticle illumination according to ambient light using the 10 available levels. Clean the lenses with a microfiber cloth and a solution suitable for optics, without abrasive products. Store the scope in a dry case after use to preserve the ArmorTek coating and the sealing of the system.
