Ruger 90674 Picatinny Scope Rail Black Hardcoat Anodized Aluminum Fits Ruger American Rimfire 22 LR 0 MOA

The Ruger 90674 is a one-piece Picatinny scope base purpose-built for the Ruger American Rimfire rifle chambered in 22 LR. Precision-machined from billet aluminum and finished in a durable black hardcoat anodized coating, this rail delivers a rigid, optics-ready mounting platform that accepts both Picatinny and Weaver-style rings.

Measuring 6.0" in length with a 0 MOA elevation, the 90674 bolts directly to the factory receiver mounting points on the American Rimfire, replacing the factory rail with a one-piece design that provides a stable, repeatable return-to-zero for your optic. Installation is straightforward using the included (4) T-10 torx mounting screws; Ruger specifies a torque setting of 15 in-lbs on the aluminum rail hardware. Rings are sold separately.

Built specifically for the 22 LR American Rimfire, this rail is not compatible with the 17 HMR chambering, which uses a different factory rail footprint. Whether you are running a rimfire red dot for plinking at the range or mounting a traditional scope for varmint hunting, the Ruger 90674 gives your optic the rock-solid foundation it needs.
