The XS Sights Standard Dot Tritium Revolver Night Sight for Colt Viper is a purpose-built upgrade for shooters who need reliable sight visibility in any light condition. This front sight combines a tritium vial with a photoluminescent glow dot to give you a bright, high-contrast sight picture whether you're shooting in daylight or low-light scenarios. If you carry a Colt Viper revolver for defense or sport shooting, moving beyond factory brass sights to a dual-illuminated front sight measurably improves speed and accuracy when it matters.
Tritium self-illuminates for 12 years without batteries or charging—a feature that matters when you need to find your sights in complete darkness. The photoluminescent dot absorbs ambient light during the day and glows when light fades, so you're never left guessing your sight alignment. The green-illuminated design delivers exceptional contrast in bright conditions and remains visible as light drops, making sight acquisition faster and more intuitive than traditional iron sights.
Built from CNC-machined steel, this sight is engineered to withstand the recoil and wear of regular shooting. The Standard Dot front sight measures 0.140" in height and threads directly onto your Colt Viper with a set screw. Installation is straightforward—the kit includes the front sight, blue threadlocker, hex wrench for the set screw, and detailed instructions. This is a genuine upgrade over factory equipment, not a cosmetic swap.
