Heckler and Koch Night Sight Set Features The Heckler and Koch Night Sight Set replaces the painted on white rings found on standard factory sights with Night Fision s patented Perfect Dot design. Rather than relying on paint that fades and chips over time the sleeve itself is injection molded around the tritium vial creating a ring that stays bright and legible for years of carry and use. This added daytime florescence makes the sights easy to pick up quickly in bright conditions while the tritium provides reliable low light and nighttime visibility. Night Fision builds these sights with some of the brightest tritium available on the market today. Each sight is CNC machined from high quality steel for strength and long term durability then finished in a black nitride coating that improves wear resistance and guards against corrosion from sweat moisture and daily carry. The set is built in the USA using Swiss tritium pairing domestic manufacturing with a trusted light source. It is designed to fit the Heckler and Koch VP9 VP9SK P30 P30L and P30SK pistols excluding optics ready slide variants giving HK owners a direct upgrade path. Gunsmith installation is recommended to ensure a secure properly fitted sight picture for sale at GrabAGun.
