The Viper® PST™ Gen II 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 glass-etched 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.
