This mount fits:
Ruger No.1 B Barrel Contour
Ruger No.1 S Barrel Contour

We have found that Ruger No. 1's with 24"-26" barrels typically came with B or S contour barrels. Guns that came with shorter barrels typically came with A contour barrels.

We have also found that guns in certain calibers have the holes in different locations.

The recoil pin hole location on your barrel may be different from the recesses drilled in our mount. Ruger may place their recoil pins in different locations for different calibers. Our mount will still function properly with just the rear recoil lug and the mounting screws. Our mounts are designed to use the mounting screws as the primary recoil lugs.

This base is NOT Compatible with the Ruger #3.

Compatible with Picatinny or Weaver scope rings.
The scope mount mounts flush on the stock recoil pins in the barrel.

We recommend measuring the hole spacing in your receiver to confirm it matches with the dimensions we have published.

Picatinny cross slots run the full length of the rail, which gives the shooter flexibility when mounting scope rings and other accessories. Our one-piece scope mounts are the obvious choice for hunters and tactical shooters alike.

We machine these in our shop using one of our machining centers. After machining, the mounts are tumbled, sand blasted, and Type III anodized for long lasting durability.

Installation: We recommend 20 inch lbs of torque and a drip of blue loctite (loctite is available through our website and is sold separately).

The entire mount and accessories (from the mounting screws and wrench down to the packaging) are made in the USA.
