The Vortex Viper HD 5–25x50 FFP VMR-4 MOA is built
for shooters who need dependable accuracy at distance with a clear and
consistent sight picture. Designed for long-range use, it combines a wide
magnification range with a detailed reticle and precise turret system.
The 5–25x magnification range allows the optic to
perform across varied shooting distances. Lower magnification offers a broader
field of view for observation, while higher magnification provides the detail
required for precise shot placement at extended range.
At its core is the VMR-4 MOA reticle in the first focal
plane, which scales with magnification. This ensures that holdover and wind
correction values remain accurate at any zoom level, allowing the shooter to
apply corrections without relying on a fixed magnification setting.
The scope features exposed turrets with 1/4 MOA
adjustments, delivering repeatable and controlled changes. The elevation
turret includes a zero stop system, enabling quick return to a preset
zero after dialing for distance. A locking mechanism helps maintain settings
during movement and transport.
An illuminated reticle improves visibility in
low-light conditions, helping maintain a clear aiming point when contrast is
reduced. The optical system uses HD glass and advanced coatings to provide a
sharp image with consistent clarity across the magnification range.
The 50mm objective lens supports image brightness
while maintaining a balanced profile. The scope is constructed from a
single-piece aluminium tube for durability and alignment stability, and it is
sealed to resist moisture and environmental exposure.

Reticle
VMR-4 (MOA)

Designed to maximize long-distance shooting and ranging
abilities, the VMR-4 reticle can be used to effectively determine ranges,
holdovers, windage corrections, and moving target leads. Ultra-precision laser
etching on the glass reticle ensures that specifications are kept to the
tightest tolerances possible. The fine center crosshair subtensions on the
VMR-4 reticle were carefully chosen to provide the optimum balance between
precision aiming and low-light visibility. Includes windage reference dots on
drop lines.
