The gloss black Top Mount Base #49A 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.
Rear Base for:
- Beretta Mato
- Winchester 70 Long Action with different hole spacing
- 70 Super Express
Note: The handiest way to pinpoint the correct base for the Winchester 52 and 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. If the hole spacing is different, then for model 70 use 47+ 46 and for model 70 use 49A+ 46
