The Vortex Viper PST Gen 2 is a serious precision optic with a 3-15x44 first focal plane setup that works up close and at distance. I like the laser-etched turrets, adjustable parallax, and RZR Zero Stop for repeatable dialing, plus the illuminated reticle with multiple intensity settings. It’s also built to take abuse with waterproof, fogproof construction and protective lens coatings.
