Leupold 178128 STD One-Piece Scope Base Springfield 1903 A3 Matte

The Leupold steel standard bases and rings are the most versatile of any mounting system we offer. The rear ring is secured by windage adjustment screws allowing the scope's internal adjustments to be reserved for precise sight-in. Additionally shims can be used for gross elevation adjustment reserving the scope's elevation adjustment for bullet drop compensation dial applications.
