The Ruger American Rifle Picatinny Scope Base for long action rifles (brand part no. 90672) is a one-piece scope base made in the USA and precision-machined from billet aluminum specifically for long action Ruger American Rifles. Ruger cuts the base to MIL-STD Picatinny slot-and-rail spacing, so it accepts either Picatinny or Weaver scope rings depending on what you already own. The base measures 6 inches long and wears a hardcoat anodized finish for corrosion resistance, and it ships complete with four TORX mounting screws and a T-10 wrench so you have everything needed for installation.
