Overview
The Vortex Viper HS is a 2.5-10x44 second focal plane riflescope built around a Dead-Hold BDC reticle for hold over shooting at varying ranges. It sits on a 30mm main tube with capped, quick reset turrets for return to zero use in the field.
Vortex markets this in its Hunting & Shooting line, and owner comparisons below put the optics up against pricier glass. XD extra low dispersion glass and XR multi coated lenses are meant to carry light from dawn to dusk, while Armortek coating protects the exterior lenses and argon purging keeps the scope fog and waterproof. It's backed by Vortex's transferable lifetime VIP warranty.
- 2.5-10x44 configuration with 4x zoom range
- Dead-Hold BDC reticle for range estimation
- 30mm main tube with capped quick reset turrets
- Argon purged, Armortek coated exterior lenses
Who it's for
Suits a hunter or shooter who wants clear glass and hold over capability at a mid tier price rather than the cost of flagship European optics. Less ideal for someone who wants a first focal plane scope for precise ranging at every magnification, since the reticle here is second focal plane.
Pros and cons
- Glass clarity rated close to pricier Zeiss models by owners who compared them directly
- Backed by Vortex's transferable lifetime VIP warranty
- Argon purged, waterproof and fogproof construction
- Magnification ring described as stiff by one reviewer
- Eye box described as average for the price range
Performance notes
XD glass and XR coatings are what several owners credit for edge to edge sharpness and strong light transmission into low light.
