Overview

This low-profile offset mount is built for attaching Scout-style weapon lights to KeyMod handguards in a 45-degree position, helping place illumination where it is needed without occupying a Picatinny rail section. It is designed for the Surefire M300 and M600 Scout lights and also works with Arisaka 300 and 600 series lights, plus the Streamlight Protac Rail Mount 1, 2, and HL-X. By replacing the factory Picatinny adaptor, it offers a compact mounting solution for hunters and shooters who want a cleaner light setup on a rifle or carbine. The black finish and slim profile keep the package restrained and purpose-driven, with fitment limited to KeyMod platforms.

Considerations & Trade-offs

  • Designed for KeyMod only, so it is not a universal light mount and requires a compatible handguard interface.
  • Intended for Scout-style lights and the listed compatible models, so fit is more specific than a general-purpose lighting solution.
  • The low-profile offset design replaces the factory Picatinny adapter, which may not suit users who want a traditional straight-ahead light position.
  • At 0.4 oz and 0.20" thick, it is built to stay compact, but that also means it is a dedicated accessory rather than a multi-use mounting platform.
