What our Experts Think
-
Built for precision long-range shooting
The 5–25x magnification range is ideal for PRS, target shooting, and extended-distance engagements, offering detailed target visibility across a wide range of distances
-
Second Focal Plane (SFP) = cleaner sight picture
Reticle remains consistent in size, providing a clear, uncluttered view at all magnifications—best suited for shooters who primarily use max zoom for holds
-
EBR-4 MOA reticle = precise but user-friendly
Features MOA-based hash marks for ranging, holdovers, and wind calls, balancing precision with readability for real-world shooting
-
Excellent glass quality in its class
XD extra-low dispersion glass and XR coatings deliver sharp resolution, strong contrast, and reduced glare, even in challenging lighting
-
Reliable turret system with zero stop (RZR)
Exposed tactical turrets with 1/4 MOA clicks and zero stop ensure repeatable adjustments and fast return-to-zero after dialing
-
Strong low-light performance (50mm objective)
Larger objective lens enhances brightness, making it effective for early morning or late evening shooting
-
Durable, field-proven construction
Aircraft-grade aluminum body, argon purging, and ArmorTek coatings make it shockproof, waterproof, and fogproof for rugged use
-
Well-balanced between performance and price
Delivers many “premium-tier” features (illumination, zero stop, HD glass) at a mid-range price point, making it a popular upgrade option
Q&A
Q: What is the Viper PST Gen II 5-25x50 designed for?
A: It’s built for long-range precision shooting, competition, and tactical applications where accuracy and repeatability are critical.
Q: What magnification range does it offer?
A: It features a 5x–25x zoom range, ideal for mid- to extreme-distance targeting and detailed sighting.
Q: What type of reticle does it use?
A: It uses the EBR-4 MOA reticle in a second focal plane (SFP), providing precise holdovers and consistent reticle size at all magnifications.
Q: What are the benefits of the SFP design?
A: The reticle remains the same size across zoom levels, offering a clean sight picture—best for shooters who dial adjustments and use max magnification for accuracy.
Q: How accurate are the adjustments?
A: It offers precise 1/4 MOA click adjustments with up to 70 MOA elevation and 35 MOA windage travel for fine-tuned long-range corrections.
Q: Does it include a zero-stop system?
A: Yes, the RZR™ Zero Stop system allows quick and reliable return to your zero after dialing elevation.
Q: How is the optical performance?
A: XD extra-low dispersion glass and XR™ fully multi-coated lenses deliver bright, sharp images with excellent color accuracy and contrast.
Q: Is it good for low-light shooting?
A: Yes, the 50mm objective lens and illuminated reticle provide strong performance in low-light conditions like dawn or dusk.
Maintenance Tips
-
Clean lenses gently: Use a microfiber cloth or lens pen to protect fully multi-coated optics and maintain HD clarity.
-
Check mounting torque: Ensure rings and base are properly secured to maintain zero under recoil.
-
Inspect turrets regularly: Verify smooth elevation and windage tracking with accurate return-to-zero.
-
Keep lenses covered: Use flip caps to prevent dust, scratches, and environmental wear.
-
Avoid harsh chemicals: Only use optics-safe cleaning solutions to preserve lens coatings.
-
Store in a cool, dry place: Supports internal seal integrity and long-term durability.
-
Confirm zero periodically: Especially after transport or heavy shooting sessions.
