Overview

This low-profile light mount is built to position a Scout-style weapon light at a 45-degree angle for a cleaner setup on compatible KeyMod handguards. It is designed for Surefire M300 and M600 Scout lights, and also works with Arisaka 300 and 600 series lights as well as Streamlight Protac Rail Mount 1, 2, and HL-X models. By replacing the factory Picatinny adaptor, it offers an offset mounting option that keeps the light tucked in close to the rifle. For hunters and shooters who want a compact, purpose-built light placement without extra bulk, it provides a straightforward mounting solution.

Considerations & Trade-offs

  • Designed for KeyMod rather than M-Lok, so compatibility depends on the handguard system you’re using.
  • Intended for specific Scout-style lights and compatible models, so it is not a universal light mount.
  • The low-profile offset design replaces the factory Picatinny adaptor, which may not suit users who want a standard rail-mounted setup.
  • At 0.4 oz, it is very light, but the compact form factor leaves little margin for applications that need more mounting flexibility.
