The Ruger 10/22 Scope Base Adapter (brand part no. 90329) is a factory-pattern scope base machined from aluminum and finished in a blued finish, purpose-built for the Ruger 10/22. It uses a Tip-Off/Weaver mounting pattern, so it accepts either Tip-Off style rings or standard Weaver-style rings, giving you more flexibility than a base cut for only one ring system. Measuring about 7.45 in. long, it mounts directly to the 10/22’s receiver for a solid, repeatable zero. This base is sold on its own, one per box, with rings purchased separately.
