XS Sight Systems Tritium Night Sight Yellow Dot

Tritium Features

XS Tritium Night Sights offer the best front sight visibility in all lighting conditions, combining tritium with XS’ patent pending glow dot. Upgrade your J-Frame 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.

The XS Big Dot tritium night sight is precision machined in Fort Worth, TX. The Big Dot demands your attention – even in high stress and for those with poor eyesight, aids in rapidly achieving combat effective hits. Outside diameter of Big Dot is 0.188″. Day-Light, Half-Light, or Low-Light, just center the dot over your target within 15 yards.
