Overview
The Vortex Viper 6.5-20x50 is a second focal plane riflescope built on a 30mm tube with a Dead-Hold BDC reticle for holdover shooting. Suits long range hunters and varmint or target shooters who want capped turrets and side-focus parallax adjustment.
This model sits in Vortex's mid tier lineup, aimed at shooters who want more magnification than a basic 3-9x hunting scope without stepping into tactical-tier pricing. The side parallax knob and capped reset turrets keep field controls simple rather than requiring constant dialing. One reviewer's field test at 660 and 760 yards, then a return to a 100 yard zero, is the kind of practical check this scope is built to pass.
- 30mm main tube with hard anodized finish
- Argon purged, O-ring sealed for fogproof and waterproof use
- Capped reset turrets for return-to-zero
- Backed by Vortex's transferable VIP warranty
Who it's for
Long range hunters, predator and varmint shooters, and target shooters who need magnification up to 20x with parallax correction will get the most from this scope. Hunters who only shoot inside 150 yards do not need this much glass and would be better served by a lower powered scope.
Pros and cons
- Holds zero after repeated field use
- Side parallax knob speeds up range adjustments
- Dead-Hold BDC reticle works for holdover without dialing
- Image reportedly softens above 12x magnification
- No illuminated reticle
