Weaver 99480 Multi-Slot Base Winchester 70 Long Action Extended

The Weaver 99480 Multi-Slot Base transforms Winchester 70 long action rifles into precision platforms with extended mounting options. This black anodized aluminum base provides additional forward mounting positions compared to standard two-piece rings, enabling optimal scope positioning for long-range applications.

What Makes This Different

The continuous rail design eliminates potential alignment issues between separate ring bases while providing 20% more mounting real estate than standard configurations. Precision-machined slots accommodate various ring spacings, allowing shooters to achieve proper eye relief with scopes of different lengths.
