The K6s fiber optic sight system pairs a high-visibility fiber optic front sight with a low-profile rear sight to deliver an ultra-high-contrast sight picture, ideal for fast target acquisition. The rear sight's low-profile design aligns with the frame, reducing snagging potential, making it a top choice for concealed carry and target shooting. Compatible with all K6s models, the rear sight is windage adjustable with a set screw lock and the front sight requires drilling and pinning. Not compatible with K6xs models.
