Original Weaver Extruded Scope Base for Ruger 10/22 This base is grooved for both Weaver style rings and the smaller rimfire groove rings. It used to be common for .22 scopes to have skinny tubes and narrow ring clamps. Nowadays shooters realize you need just as good a scope for rimfire as you do for centerfire. This base allows both approaches to scoping your Ruger 10/22. Available in Black or Silver finish. Click Here to see all of our Ruger 10/22 Scope Mounts and Scopes!
