The R3D represents a thoughtful approach to defensive sighting. This is a true 3-dot night sight system designed to function across the full spectrum of lighting conditions—from bright daylight to complete darkness.
The front sight employs a dual-function approach. A green photoluminescent glow dot surrounds a central tritium vial, creating a sight picture that adapts to your environment. In daylight, the photoluminescent ring provides a vibrant aiming point. As light fades, the tritium vial glows with its characteristic green light, ensuring visibility when ambient light fails. This combination eliminates the need to choose between daytime and low-light performance.
The rear sight features two tritium vials positioned for quick low-light indexing. The blacked-out rear face creates essential contrast with the bright front sight, allowing for rapid sight alignment under any conditions. The wide notch design promotes fast sight acquisition and smooth front-sight tracking, whether you're shooting in sunlight or relying on artificial light.
These sights fit the following platforms:
This sight system prioritizes speed and reliability. The wide rear notch and prominent front sight work together to minimize sight alignment time. Whether you're training at the range or preparing for defensive use, the R3D delivers consistent performance across all lighting conditions.
