From XS Sights . . .
XS Sights is excited to introduce R3D 2.0 tritium night sights. These new and improved second-generation R3D notch and post tritium sights are engineered to give gun owners a brighter, stronger set of self-defense sights that are even easier to install than the original models and built to withstand years of EDC use and abuse.
Designed to drive focus downrange, the new R3D 2.0 sights feature significant improvements from their gen 1 counterpart.
