Overview

This two-piece scope base is designed for bolt-action rifles where access to the magazine or breech area matters during setup and use. Its reversible rear style offers flexibility for mounting options, and the matte black finish keeps the look understated on the rifle. It is listed for Winchester 70, 670, 770, and 70A actions, and it works with both right-hand and left-hand configurations. For hunters who want a practical mounting solution with a cleaner profile than a one-piece setup, it provides a straightforward option without adding unnecessary complexity.

Pros

  • Two-piece base design allows access to the magazine or breech area.
  • Reversible rear style supports flexible mounting options.
  • Fits Winchester 70, 670, 770, and 70A models.
  • Compatible with both right-hand and left-hand actions.

Considerations & Trade-offs

  • Two-piece bases leave the action more open than a one-piece setup, which can be helpful for loading and access, but they also mean the mounting system is split across two points rather than one continuous base.
  • This model is specific to Winchester 70, 670, 770, and 70A actions, so fit is limited to those compatible rifles.
  • The reversible rear design adds mounting flexibility, but it also means correct orientation and setup matter when installing.
  • Matte black finish offers a subdued look, though it may not match every rifle or ring finish exactly.
