The Top Mount Base #96 (Gloss Black) from Weaver has been machined to tight tolerances for a custom fit. This aluminum base offers maximum strength so that the rings will hold tight.
Compatibility
Note: The handiest way to pinpoint the correct base for the Winchester 52 & Winchester 70 Long Action Rifles is to check the spacing of the tapped holes for the rear base and compare it to the hole spacing for the front base. For hole spacing the same, Model 70, use 47+ 46.
