Weaver 48335 Multi-Slot Base 430T Black for Ruger 10/22 Rifles

The Weaver 48335 Multi-Slot Base transforms your Ruger 10/22 into a versatile optics platform with secure Weaver-style mounting capability. This precision-machined base replaces the factory scope mounts and provides multiple positioning options for scopes, red dots, and tactical accessories.

What Makes This Different

Unlike single-position bases, the 430T features multiple cross-slots that allow forward and rearward scope positioning to achieve proper eye relief with various optic configurations. The base mounts directly to the factory drilled and tapped holes in the 10/22 receiver without requiring gunsmithing or permanent modifications. This design maintains the rifle's original profile while adding professional-grade mounting capability.
