Ruger 90329 Scope Base Adapter Black Aluminum Fits 10/22 & 22 Charger - Tip-Off/Weaver Mount

The Ruger 90329 Scope Base Adapter is a factory one-piece optic mount purpose-built for Ruger 10/22 rifles and 22 Charger pistols. Machined from lightweight aluminum and finished in a durable black powder coat, this adapter gives you a rock-solid optics platform on any 10/22 or Charger with the factory-drilled and tapped receiver pattern.

The combination Tip-Off/Weaver base accepts both Tip-Off and Weaver-style rings, so you can pair it with a wide range of red dots, hunting scopes, and other optics without buying a separate base for each ring standard. Installation is straightforward using the included four mounting screws. The adapter drops onto the factory receiver holes and secures in place with no permanent modification or gunsmithing required.

This is the genuine Ruger factory scope base adapter, not an aftermarket copy. Rings are not included, letting you choose the ring style and height that best matches your optic and shooting application. Whether you are mounting a red dot for plinking, a hunting scope for the field, or a magnified optic for precision rimfire work, the 90329 provides a reliable, low-profile foundation.
