EGW
The EGW Ruger No. 1 scope base is a precision-machined one-piece Picatinny rail system designed specifically for Ruger No. 1 B and No. 1 S rifles. Built from ultra-rigid 7075 T6 extruded aluminum, this heavy-duty mount integrates directly with your rifle's factory recoil pin locations—no drilling or tapping required. Whether you're setting up a long-range hunting rig or a precision target rifle, this base gives you the versatility to quickly adjust eye relief and swap between Picatinny or Weaver scope rings to dial in your preferred optic.
EGW engineered these bases to sit 0.100" lower than their lightweight counterparts, which keeps your scope closer to the barrel centerline for a lower bore axis—a real advantage if you're chasing improved accuracy on the bench or in the field. The full-width Picatinny cross-slots are gauged to MIL-STD 1913 specifications to a tolerance of +/-.002", meaning your rings will seat consistently and repeatably every time you mount or remount.
Installation is straightforward: the base comes with socket head Torx screws and the wrench you need to install them. EGW recommends torquing to 20 inch-lbs and applying a small amount of blue Loctite to the fasteners. This approach prevents creep while staying easy to adjust if needed down the road. Just note that this base is engineered exclusively for the Ruger No. 1 B and No. 1 S—it won't fit No. 3 models or other platforms.

This base is designed exclusively for Ruger No. 1 B and No. 1 S rifles. It mounts directly to the factory recoil pin holes on the barrel. It will not fit Ruger No. 3 models or other platforms.
This base accepts any scope rings built to Picatinny or Weaver specifications, giving you flexibility to choose rings that match your budget and preferred eye relief position.

The 0.100" lower profile brings your scope closer to the barrel centerline, which can improve accuracy potential by lowering the bore axis. This is especially valuable for precision shooting at distance or on the range.
