Q&A
Q: What is the Viper PST Gen II 1‑6x24 designed for?
A: A versatile LPVO (Low Power Variable Optic) ideal for tactical shooting, competition, and close-to-mid range engagements.
Q: What makes the 1–6x magnification useful?
A: True 1x enables fast, red-dot-like targeting, while 6x magnification allows for precise shots at extended distances.
Q: Is this a First or Second Focal Plane scope?
A: It is a Second Focal Plane (SFP) scope, meaning the reticle remains the same size and is optimized for use at a specific magnification.
Q: What reticle options are available?
A: Common options include VMR-2 (MOA or MRAD) reticles, designed for fast target acquisition and accurate holdovers.
Q: Is the reticle illuminated?
A: Yes, it features daylight-bright illumination with multiple intensity settings, ideal for all lighting conditions.
Q: How is the optical performance?
A: Equipped with XD glass and fully multi-coated lenses, delivering clear, bright images with excellent contrast.
Q: What turret system does it use?
A: Features low-profile capped turrets with precise, repeatable adjustments for reliability in the field.
Maintenance Tips
-
Clean lenses with care: Use a microfiber cloth and lens-safe cleaner to preserve fully multi-coated optics and maintain sharp, high-contrast images.
-
Keep turrets debris-free: Regularly wipe exposed tactical turrets to ensure smooth 0.1 MRAD adjustments and reliable tracking.
-
Check zero-stop (RevStop™): Periodically verify zero return for consistent long-range accuracy and repeatability.
-
Inspect mount & 34mm tube fit: Ensure rings are properly torqued to prevent shift and maintain zero under recoil.
-
Maintain parallax & focus controls: Keep side parallax (15 yards–∞) and fast-focus eyepiece clean for precise targeting.
-
Use throw lever correctly: Keep it secure and clean for quick, smooth magnification changes from 5x–25x.
-
Protect lenses & coatings: Avoid touching glass—ArmorTek coatings resist scratches but still require careful handling.
-
Dry after exposure: Even though waterproof, fogproof, and nitrogen-purged, wipe down after rain or dust.
-
Store with accessories: Use included lens covers and sunshade to protect the 56mm objective from damage.
-
Avoid impacts: Rugged construction is shock-resistant, but minimizing drops preserves internal precision.
