Overview

Built for M-Lok handguards, this low-profile light mount is intended to replace a standard Picatinny rail adapter and give shooters a cleaner way to position compatible weapon lights. It is designed for use with Surefire Scout Lights, Modlite PLH and OKW models, Arisaka 300/600/18650 Series lights, Streamlight Protac Rail Mount lights, and the Olight Odin. The mount also tucks the light under either side of ATPIAL laser/illuminator units and is made to clear the QD lever on Steiner DBAL I2, A3, and D2 devices. For hunters and other field users building a compact rifle setup, it offers a streamlined mounting option where space around lasers and accessories is limited.

Considerations & Trade-offs

  • Designed for specific light families and laser/illuminator setups, so compatibility should be checked against your exact equipment before purchase.
  • This mount is built for M-Lok handguards and replaces the stock Picatinny rail adapter, so it is not a universal solution for other mounting systems.
  • Its low-profile layout tucks the light underneath either side of supported laser/illuminator units, which may be beneficial for clearance but is more specialized than a standard rail-mounted setup.
  • Finish is listed as FDE, so it may not match every rifle build or accessory color scheme.
