Overview

Built for hunters and shooters who want quick, repeatable attachment of compatible accessories, this clamp adds a 3-position lever-release system to the ARCALOCK platform. The reversible lever arm lets you set the clamp for clamped, sliding, or fall-off operation, giving you more control over how the mount interfaces with your setup. It is designed around the 17S mounting footprint, so it works with a range of existing accessories from brands such as Atlas, Thunderbeast Products, Two-Vets Tripods, and Harris Bipod Adapter Kits. For field use where fast changes and secure lockup matter, it offers a practical mounting option without adding unnecessary complexity.

Pros

  • 3-position reversible lever arm offers clamped, sliding, and fall-off settings.
  • Compatible with existing accessories using the 17S mounting footprint.
  • Steel adjustment knob is built for long-term reliable use.
  • Milled stainless steel lever arm adds a robust construction detail.
  • Quick-detach design adds mounting versatility within the ARCALOCK system.

Considerations & Trade-offs

  • The 3-position lever release adds flexibility, but it also means you’ll want to set it intentionally for the way you plan to use the mount.
  • Compatibility is tied to existing accessories with a 17S mounting footprint, so it’s best suited to setups already built around that standard.
  • This is a clamp-only component, so it’s an add-on for ARCALOCK systems rather than a complete mounting solution on its own.
  • The reversible lever arm offers configuration options, but that also introduces another setup choice to confirm before field use.
