Overview

Built for hunters setting up a Marlin 336, this cross-slot base provides a straightforward mounting platform for optics that use Picatinny- or Weaver-style rings. Its 7075-T6 aluminum construction and matte black finish keep the profile clean while supporting a short-action rifle setup. Mounting hardware is included, and rings are not, allowing you to choose the ring style that matches your optic and preference.

Pros

  • Designed specifically to fit the Marlin 336 rifle.
  • Accepts both Picatinny- and Weaver-style rings.
  • Made from 7075-T6 aluminum for a lightweight mount.
  • Cross-slot design offers flexible ring compatibility.

Considerations & Trade-offs

  • Rings are not included, so the mount is only one part of the setup and requires compatible rings to complete the optic installation.
  • This base is specific to the Marlin 336, so it is not a general-purpose option for other rifles.
  • The short-action design and 5.90" length make fitment more specific, which is useful for the intended rifle but less flexible for other configurations.
  • Mounting hardware is included, but the matte black finish and cross-slot style are functional rather than decorative choices.
