XS Sights The XS Standard Dot Ember upgrades an LCR to a high-contrast front sight that absorbs light and glows in less than ideal conditions. Optic Yellow is the best option for low light and has the brightest glow intensity. Primarily based on the white light spectrum, optic yellow is very reflective and will excite the photoluminescent properties of the dot faster than any other color. The increased surface area of the convex dot increases light absorption, intensifying the charge of the glow properties of the dot. Fits Ruger LCR in .38 or .357 (not 9mm, .22LR, .22WMR, or .327 FedMag). Precision machined in Fort Worth. Outside Diameter Standard Dot 0.140", fits in common holsters. Sight pre-drilled and comes with new retaining pin and thread locker, gunsmith installation recommended. RP-0013N-1Y
