Introducing the Shield SIS (switchable interface sight), enhancing your precision with the convenience of 4 switchable reticles and touch-button brightness adjustments. Our sights now automatically adjust brightness for optimal visibility in any environment, with an added manual mode offering 12 brightness levels for tailored performance. Like our flagship CQS, the SIS features an automatic light meter to prevent reticle flaring, ensuring clarity in varying light conditions. For scenarios where your target is in bright light while you're in darkness, our new manual brightness adjustment provides precise control over reticle illumination. With the press of a button, switch between 4 reticle options for mission-specific setups, backed by Shield's technology that maintains reticle accuracy without relying on moving parts. The SIS represents the next evolution in our combat-proven lineup, shaped by customer feedback from Special Forces, Law Enforcement and Military users worldwide. At just 2.16 oz, it continues our legacy of being the smallest, toughest and lightest in its class, pushing the boundaries of technology while reducing weight for enhanced performance.
