    Vortex Viper PST Gen II 3-15x44, 30mm Tube, Tactical Turrets EBR-4 MOA Reticle


    This updated favorite hands an unfair advantage to shooters who seek to keep the upper hand in every situation from close quarters to long-range shots. The illumination dial is cleanly integrated into the side focus adjustment knob for easy access and streamlined performance. The reticle offers shooters highly functional, intuitive, and detailed hold points, yet remains uncluttered for optimal viewing and features 10 intensity levels with off positions between each setting.
