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.
What buyers say
From Amazon customer reviews.
Buyers who mount this scope for long range hunting and target work consistently mention it holds zero after months of field use, including one owner who tracked point of impact after shooting at 660 and 760 yards before returning to a 100 yard zero. Several reviewers compare it favorably to pricier glass from other brands. One buyer flagged that clarity drops off somewhat above 12x magnification, and Vortex's warranty service, including a free replacement turret cap for one owner, got a specific mention as a plus.

Drawn from this product's published specifications.
- Holds zero after repeated field use
- Side parallax knob speeds up range adjustments
