If you're looking to mount an optic on your Ruger 22/45 pistol, the Ruger Weaver Style Pistol Scope Base Adapter gets the job done without complications. This is a genuine Ruger factory accessory designed specifically for 22/45 models, giving you a straightforward way to add a scope or red dot to your rimfire platform. It's a simple, no-fuss solution for shooters who want to improve precision on the range or in the field.

The adapter is machined from aluminum and finished in black anodize, so it'll hold up to regular use and won't add unnecessary weight to your pistol. The Weaver-style mount pattern is one of the most common and versatile optic mounting standards, opening up your options for compatible rings and sight systems. Just remember: this base adapter works with standard Weaver rings—it does not fit Ruger scope rings, so verify your ring choice before ordering.

Whether you're building out a 22/45 for casual plinking, small-game hunting, or precision rimfire work, this adapter is the foundation you need. It's the kind of straightforward accessory that works reliably and lets you focus on shooting, not wrestling with fitment issues.
