Weaver #S430 (48249) Steel Top Mount Base (Matte Black)
Weaver's precision-built steel bases are machined to tight tolerances for a custom fit. A square-cut notch mates to the sturdy cross bolt in every Weaver® top mount Ring. Custom-hardened fastening screws included
Rear base for:
- Beretta Mato
- Winchester 70 Long Action with hole spacing different & 70 Super Express
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.
If the hole spacing is different, then for model 70 use 47+ 46 and for model 70 use 49A+ 46
