Seamless mode switching between white light and infrared is achieved with a no-look self-locking selector ring, ensuring quick adaptation in high-stress moments, while integral ambidextrous momentary and constant-on switching provide reliable access during rapid engagements. Whether operating with night-vision devices for stealth missions or needing a dependable illumination tool for dynamic encounters, the X300V-B stands out as a robust, battle-tested solution that enhances target acquisition, navigation, and safety in demanding environments.
