Overview

Built for rifles that need a compact light setup, this mount is intended to replace the standard Picatinny adapter with a lower-profile option for compatible Scout-style weapon lights. It is designed for use with the Surefire Scout Light M600 and M300 series, Modlite PLH and OKW, Arisaka 300/600/18650 series, Streamlight Protac Rail Mount 1, 2 and HL-X (non-laser), and Olight Odin. The layout is meant to tuck the light underneath either side of NGAL, ATPIAL-C, AN/PEQ15, and LA-5/PEQ laser/illuminators, while also allowing clearance for the QD lever on Steiner DBAL I2, A3, and D2 units. Primarily intended for the SIG MCX and MPX, it also fits well on B&T GHM and APC series and CZ S Mfg platforms.

Considerations & Trade-offs

  • Designed specifically for M-Lok handguards on MCX and MPX platforms, so fitment is more specialized than a universal light mount.
  • It replaces the stock Picatinny rail adapter, which means it is intended for setups that can use this lower-profile mounting approach rather than standard rail mounting.
  • Compatibility is limited to the listed weapon light models and laser/illuminator configurations, so it may not suit lights outside those specified.
  • The mount is positioned to tuck the light under certain laser/illuminator units and clear specific DBAL QD levers, so users should verify their exact accessory layout before ordering.
