Note: For the Mauser Receiver Ring about 1.410" Diameter (98FN) shimming is probably required for a perfect scope alignment. The rear base may require modifications for correct fit to military actions

Extension base allows an extra .689"
Note: The Winchester 52 (hole spacing same) may require bolt and/or safety alteration, without which the firearm will not function safely and properly. Consult with a qualified gunsmith.
The handiest way to pinpoint the correct base for the Winchester 52 is to check the spacing of the tapped holes for the rear base and compare it to the hole spacing for the front base. When the hole spacing is the same, for Model 52, use 25+ 57.
