Shoot better day and night with the XS F8 Night Sights. These sights increase front sight focus by utilizing a large, high-contrast green front sight for fast sight acquisition. The wide notch rear sight easily aligns with the front sight, enhancing visibility.XS F8 Night Sights provide a notch and post solution for quick sight acquisition in various lighting conditions.
