Quick-Attach M-LOK Handguard to Suit Your Mission

The Switch Mod 1 handguard from Fortis features a unique lever system, which allows quick installation and detachment of your handguard.  The robust 7075-T6 aluminum lever interfaces with a heat-treated barrel nut, making a robust attachment system.

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.

Currently we offer two lengths, which are ideal for two types of popular AR-15 builds.  The 15.3″ version fits perfectly on a 16″ barrel, giving you full coverage while having near-flush fit for a suppressor mount.  The 9.6″ version works best on a 10.3″ or 10.5″ barrel, again producing a minimal gap between the end of the handguard and a suppressor.

The Mod 1 also features a full-length top rail, 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.
