The Vortex Viper PST (Precision Shooting Tactical) Riflescope sports all the characteristics associated with top-tier riflescopes but with a highly economic price. With matching reticle and turret measurements, the Vortex Viper PST is capable of making incredibly fast and accurate dialing of shots. In addition, the Viper PST’s lenses are constructed with extra-low dispersion glass for enhanced resolution, and have been given Vortex’s proprietary XR Fully Multi-Coated lens treatment for increased light transmission as well as having anti-reflective properties.
