The Ruger American Rifle 20 MOA Scope Base (brand part number 90678) is a one-piece base built specifically for the Ruger American bolt-action rifle, adding 20 minutes of angle to help long-range shooters run out their scope’s elevation adjustment on distant targets. Ruger machines the base from aluminum and finishes it in a traditional blued finish, with a Picatinny-pattern rail that accepts Weaver-style rings for mounting. Because it’s cut specifically for the Ruger American action, installation is a straightforward, no-fitting bolt-on job.
