Sight blades are precision-engineered from a high-tensile strength, corrosion-resistant alloy. The dovetailed windage and elevation adjustments feature hardened gib locks, allowing for rapid modifications by loosening a single screw. No barrel dovetailing is required. Blades are sold separately and can also serve as replacements for the aperture on WGRS sights. The product features a black anodized finish on aluminum, providing a sleek, durable, and corrosion-resistant surface that enhances both aesthetics and longevity
