Overview

Built for hunters setting up a Remington 700 Long Action, this one-piece cross-slot base provides a stable mounting platform for optics that use Picatinny- or Weaver-style rings. The included 8-40 screws and 20 MOA cant make it a practical choice for scoped rifle setups where elevation adjustment is part of the plan. Made from 7075-T6 aluminum, it keeps the mount lightweight while staying within the BackCountry line’s intended rugged use. It is a straightforward option for anyone prioritizing a secure scope-to-rifle connection without unnecessary bulk.

Considerations & Trade-offs

  • Designed specifically for a Remington 700 Long Action, so it is not a universal base and should be matched to the correct receiver.
  • The 20 MOA cant is a deliberate setup choice; it adds elevation bias for certain optics setups but may not suit every hunting application.
  • It accepts Picatinny- and Weaver-style rings, but ring choice still needs to match the rest of the mounting system and optic tube.
  • The included 8-40 screws are part of the package, but installation still depends on proper torque and correct receiver compatibility.
