Weaver Top Mount Base 40A Scope Base – Remington 700/Ruger M77/Weatherby Mark V

The Weaver Top Mount Base 40A is a one-piece aluminum scope base built for bolt-action hunting rifles that need a rock-solid, no-slip platform for a Weaver-style ring set. It's the base a Remington 700, Ruger M77 or Weatherby Mark V owner reaches for when they want their zero to stay put shot after shot in the field.

This base uses Weaver's cross-lock design so the square-cut notch mates precisely to the cross-bolt in every Weaver detachable ring, fighting the effects of recoil. It's a one-piece aluminum base machined to tight tolerances for a custom fit, and screws are included. It mounts directly to the receiver and carries a gloss black finish to match factory rifle metal.
