The Viper PST (Precision Shooting Tactical) riflescope boasts features associated with top-tier riflescopes. Matching reticle and turret measurements allow accurate, fast dialing of shots. The one-piece 30mm tube, precision-machined from a single solid block of aircraft-grade 6061-T6 aluminum, is purged with Argon gas to eliminate internal fogging and extend the life of the optics. The optics are fully multi-coated and deliver beautiful detail and color while transmitting 95% of available light. The tactical turrets have audible clicks which allow for precise windage and elevation adjustments. Born from an intimate understanding of riflescope design, forward-thinking engineering, and open ears to a market incredibly vocal about what it wants in a riflescope, the Viper PST series delivers the performance and features tactical shooters demand at an economical price.
