The WEAVER #45 48045 Top Mount 2-Piece Base is a durable aluminum scope mount base designed for a wide range of firearms. Each Weaver base is machined to tight tolerances for a custom fit. These aluminum bases detach quickly and easily and offer maximum strength for rings to hold tight. Notes: Product is a one-piece base; some firearm types may require the purchase of both a front and a rear base. For Mauser Receiver Ring (1.4" diameter, 98FN), shimming may be required for proper scope alignment. Interarms Viscount rear base may require modifications for correct fit to military actions.
