EGW
The EGW Ruger American Rimfire scope base brings modernized mounting to a classic rimfire platform. This one-piece Picatinny rail installs directly onto your Ruger American Rimfire receiver using the factory scope mount holes—no drilling, no tapping, no gunsmithing required. If you're looking to upgrade your rimfire's optic setup with the flexibility to swap scopes or adjust eye relief without tools or headaches, this is a straightforward way to get it done.
Built from 6061 T6 extruded aluminum, the base is precision-machined to MIL-STD 1913 Picatinny specifications (±.002") and weighs as little as possible thanks to a milled center channel that runs the length of the rail. That means it'll work with any standard Picatinny or Weaver rings you already own, and you can dial in eye relief quickly without breaking anything down. The full-width cross-slots are gauged to mil spec, so mounting rings stay put and repeatable.
Installation is dead simple: the base drops into place using your rifle's existing holes, and EGW supplies everything you need—socket head Torx screws and the wrench to install them. The shop recommends 20 inch-lbs of torque and a small dab of blue threadlocker on those screws to keep things locked in.
