Lightweight M-LOK Handguard with Smooth Vented Grip Area

Like the Mod 1 Switch from Fortis, the Mod 2 M-LOK handguard features a unique lever system, which allows quick installation and detachment of your handguard.  A 7075-T6 Aluminum lever retains the handguard on a steel barrel nut, giving you a rigid lock when you’re on mission, and easy customization when you’re at the workbench.

Check out the video below to see how the quick attachment system works, and how easy it is to install this innovative M-LOK handguard.

Fortis offers three lengths, which are ideal for a variety of AR-15 builds.  The 15.3″ version fits perfectly on a 16″ barrel, the 13.8″ is deal for a 14.5″ barrel, and the 9.6″ version works best on a or 10.5″ barrel.  All versions leave a very narrow gap between the base of the threads and the end of the handguard for near flush-fit suppressor mounting.

The Mod 2 also features a top rail with a shaved-down grip area, with M-LOK slots at the 3, 6, and 9 o’clock positions.  In addition, there are extra M-LOK slots at the very end of the handguard, on the offsets.  These slots are perfect for inline light or laser mounts.
