Overview

Built for Surefire Scout Light Pro swivel bodies, this mount serves as a direct replacement for the factory M-Lok interface while giving users more flexibility in light placement. It is intended for setups that need cleaner alignment with lasers or a cantilevered position near the end of the handguard to help reduce barrel or suppressor shadow. The triangular profile is designed to resist twisting or bending, and the compact 3.0-inch, 0.8-ounce format keeps the mount low-profile. Compatible with M140A, M340C, M340V, M640DF, M640U, and M640V models, it is a purpose-specific option from Arisaka Defense for rifle setups built around the Scout Light Pro platform.

Considerations & Trade-offs

  • Designed specifically for Surefire Scout Light Pro swivel bodies, so it is not a universal light mount and should be matched to the listed compatible models only.
  • It is a drop-in replacement for the OEM M-Lok mount, which means installation is tied to that mounting interface and setup rather than a broader range of attachment systems.
  • The cantilever option can help with positioning off the handguard, but that placement may not suit every rifle setup or accessory layout.
  • At 3.0" long and 0.8 oz, it is compact, but users planning a very tight rail arrangement should account for the mount’s footprint before finalizing placement.
