Leupold Standard 1-Piece Base for 1903 A3, Matte - LEU 178128

This Leupold steel standard base is a one-piece mounting system designed for the 1903 A3 rifle platform. The rear ring features windage adjustment screws, allowing the scope's internal adjustments to be reserved for precise sight-in and elevation compensation. Shims can be used for gross elevation adjustment, preserving the scope's elevation dial for bullet drop compensation applications.
