Ruger 90674 Picatinny Rail - Black Aluminum for American Rimfire

The Ruger 90674 Picatinny Rail transforms your Ruger American Rimfire into a precision platform ready for optics and accessories. This factory rail system eliminates the guesswork of aftermarket modifications while maintaining zero MOA cant for consistent accuracy. Built specifically for the American Rimfire action, it provides a rock-solid mounting foundation that won't shift under recoil.

What Makes This Different

Unlike generic rail systems that require gunsmithing or compromise fit, this OEM Ruger rail integrates seamlessly with the American Rimfire's receiver design. The black anodized aluminum construction resists corrosion while maintaining a low profile that doesn't interfere with bolt operation. Factory engineering ensures proper spacing and alignment without the trial-and-error of universal mounts.

Key Features

• Factory-engineered fit for Ruger American Rimfire rifles
• Black anodized aluminum construction for durability and corrosion resistance
• 0 MOA cant ensures consistent scope alignment
• Standard Picatinny/Weaver rail compatibility for all major optic brands
• Low-profile design maintains clean rifle lines

This rail handles everything from lightweight rimfire scopes to heavier tactical optics without flexing or shifting point of impact. The 0 MOA specification means scopes mount level without shimming or adjustment, critical for precision shooting at extended ranges. Whether mounting a basic 3-9x scope for plinking or a high-magnification optic for competition, the rigid aluminum platform maintains zero through thousands of rounds.
