Thorntail2 M-LOK® Light Mount

Box Construction design of the light mounting pocket increases strength and reduces overall weight

Thorntail2 M-LOK® Light Mount: Saves Weight / Eliminate Components / Improve Adjustability: By removing the factory thumb-screw 1913 rail mount from Surefire’s M300, M600 Scout and Streamlight Protac Railmount 1, 2 & HL-X, directly attach your Light to Thorntail 2 via the two threaded holes in the square lugs on your Light with our included hardware.
