Why Choose R3D?

The R3D design philosophy prioritizes speed and accuracy across all lighting conditions. By making the front sight brighter and more visible than the rear sights, your eye naturally focuses downrange where it needs to be. Whether you're shooting in bright sunlight or navigating low-light scenarios, the R3D delivers the sight picture you need when you need it.
