If you're upgrading your Ruger American Rimfire with an optic, you'll need a solid mounting solution—and that's exactly what the Ruger American Rimfire Rifle Picatinny Rail delivers. This one-piece scope base is purpose-built for .22 LR American Rimfire rifles, dropping directly onto your factory receiver holes without any guesswork or gunsmithing. The rigid aluminum construction and hardcoat anodized finish mean your optics platform stays put through thousands of rounds, whether you're punching paper at the range, hunting small game, or running precision .22 drills.
The 0 MOA design works seamlessly with standard Picatinny and Weaver rings, giving you flexibility in scope selection. At 6 inches long, it spans the receiver solidly without unnecessary overhang, and the precision-machined billet construction resists flex when you're locking down quality rings. The hardcoat anodize protects aluminum from the elements—a smart choice for a rifle that might spend time in the field rather than staying exclusively in a safe.
Installation is straightforward: the four TORX screws thread into your rifle's existing holes, and Ruger thoughtfully includes the T-10 wrench you'll need right in the box. No hunting for tools or wondering if you're using the right fasteners. Whether you're setting up a first optic for a young shooter or dialing in a precision .22 build, this rail gives you a solid, repeatable foundation.

Yes—this base is engineered specifically for Ruger American Rimfire rifles chambered in .22 LR. It's designed to bolt directly into the factory scope mount holes on the receiver, with no modification required.
Any rings that follow the standard Picatinny or Weaver format will work. The MIL-STD slot-and-rail spacing is universal, so you have plenty of options from budget to premium brands.
No. The base bolts into your existing factory holes using the four TORX screws included in the box. Ruger includes the T-10 wrench you'll need, so you can install it with basic tools at home.
0 MOA means the rail mounts flat and parallel to your barrel without introducing any built-in elevation adjustment. Your scope's turrets handle all the vertical and horizontal adjustment.
