For target acquisition in a variety of situations, use the Vortex Viper PST Gen II Riflescope. The HD optical system provides sharp resolution and limits chromatic aberration, while the XR⢠Plus antireflective coating promotes light transmission for use in low-light conditions. The ArmorTek® lens coating is resistant to scratches and dirt, and the rugged shockproof construction withstands recoil and impacts. The scope is gas purged and sealed with an O-ring for waterproof and fog-proof performance, and the illumination dial allows for easy adjusting between the 10 intensity levels.
