The Leupold Standard 2-Piece Scope Base & Rings for the Cooper 38/21 (part no. 52980) bundles a matched base-and-ring kit built to that specific receiver spec, so there’s no separate ring purchase or fitment guesswork. Leupold machines the two-piece set from steel and finishes it matte, and the rear ring’s windage adjustment screws set lateral zero without touching the scope’s internal travel. Shims correct gross elevation, keeping the scope’s own dial free for fine ballistic compensation. Among scope bases for Cooper 38/21 rifles, this Standard set is the complete, fitted answer.
