Vortex Optics Viper PST Gen II 3-15x44/5-25X50 FFP EBR-7C MOA/MRAD
- The Viper PST Gen II takes incredible performance and rock solid tactical features to new heights. The 3-15x44 first focal plane riflescope is incredibly versatile and ideal for close to long range shooting scenarios.
- Shooters who dial their turrets for bullet drop and wind compensation will appreciate the laser etched turrets, adjustable parallax and the RZR zero stop. A fiber optic rotation indicator ensures you can keep track of your turret position with ease.
- The reticle offers shooters highly functional, intuitive, and detailed hold points, yet remains uncluttered for optimal viewing and features 10 intensity levels with off positions between each setting.
- Extra-low dispersion glass increases resolution and color fidelity. XR fully multi-coated lenses increase light transmission. Armortek coatings protect the lenses from scratches, oil, and dirt.
- O-ring sealed and argon purged, the Viper delivers waterproof and fogproof performance while the single-piece, aircraft-grade aluminum construction gives shooters a durable platform.

A: Features XD extra-low dispersion glass and XR fully multi-coated lenses for sharp clarity, high contrast, and excellent low-light performance.
Q: What turret system does it use?
A: Equipped with exposed tactical turrets and RZR Zero Stop, allowing precise dialing and quick return to zero.
Q: Is the reticle illuminated?
A: Yes, it offers 10 brightness levels for visibility in varying light conditions.
Q: What is the parallax adjustment range?
A: Adjustable from ~20 yards to infinity, ensuring sharp focus at all distances.
Q: How durable is the scope?
A: Built from aircraft-grade aluminum, it is shockproof, waterproof, and fogproof for rugged field use.
Maintenance Tips
-
Clean lenses with care: Use a microfiber cloth and lens-safe cleaner to preserve multi-coated optics and clarity.
-
Inspect mounts & rings: Ensure all screws are properly torqued to maintain zero and recoil stability.
-
Keep turrets clean: Remove dust/debris from elevation and windage turrets for smooth, precise adjustments.
-
Check zero-stop regularly: Verify zero-reset and tracking accuracy for consistent long-range performance.
-
Battery maintenance (illuminated reticle): Replace CR2032 as needed and remove during long-term storage.
-
Avoid direct contact with glass: Oils and smudges reduce light transmission—handle carefully.
-
Dry after exposure: Wipe down after rain or humidity despite fogproof/waterproof construction.
-
Prevent impacts: Durable build, but minimizing drops protects internal precision components.
