The Vortex Viper PST Gen II 5–25x50 EBR-4 MOA is a
long-range riflescope designed for shooters who prefer a fixed reticle size
combined with precise turret adjustments. It offers a broad magnification range
and a structured reticle layout suited to controlled shooting environments.
With 5–25x magnification, the scope adapts easily
between wider field shooting and detailed long-range targeting. Lower
magnification provides better situational awareness, while higher magnification
allows for precise aiming at distance.
The EBR-4 MOA reticle is configured in the second
focal plane, keeping the reticle size consistent across all magnification
settings. This design supports a clear sight picture and allows shooters to
apply holdover references at a chosen magnification while maintaining visual
simplicity.
Adjustment is managed through exposed turrets with 1/4
MOA click values, providing predictable and repeatable changes. The
elevation system includes a zero stop feature, allowing the turret to
return quickly to a preset zero point after dialing for range.
The scope includes reticle illumination, which can be
adjusted to suit different lighting conditions. This helps maintain visibility
when shooting in reduced light environments or against darker backgrounds.
The optical system is designed to deliver a clear and
consistent image, supporting target definition across the full magnification
range. A 50mm objective lens helps maintain brightness when using higher
magnification levels.
Constructed from a single-piece aluminium tube, the scope is
designed for durability and stability. It is sealed to protect against moisture
and environmental exposure, ensuring dependable performance during outdoor use.
