Considerations & Trade-offs

  • Designed specifically for a Remington 700 Long Action, so it is not a universal fit across other rifles.
  • The base is a one-piece, no-cant design, which limits built-in adjustment options compared with canted bases.
  • It accepts Picatinny- and Weaver-style rings, but ring compatibility still depends on the rings you choose.
  • Two screw sets are included (8-40 and 6-48), so installation requires selecting the correct hardware for your receiver.
