Fortis wanted to design a handguard that was easy to install, but also able to mount with a full 360 degrees of contact with the barrel nut. The new patent pending, two-piece barrel nut is one of a kind. Fortis developed it from the ground up and the machining time it takes to make the barrel nut, rivals the time making the actual rail. What they ended up with is a rail that not only looks amazing, but is still true to our lightweight brand. The barrel nut/mounting system keeps the rail performing even during the harshest of conditions.

  • 12.9” aircraft grade 6061-T6 aluminum rail, 4140 steel barrel nut.
  • Proprietary, patent pending 2-piece barrel nut that provides 360-degree contact.
  • Free float rail design.
  • M-LOK attachment points.
  • No visible screws on the rail system.
  • Included barrel nut wrench.
  • 1.35" internal diameter.
  • Made in the U.S.A.

Looks great, feels great


It's exactly what it looks like. It's a fancy AR handguard with Pic rails around the end. The installation is kinda weird, but just follow their videos closely and you shouldn't have any issues. Overall I am very satisfied.

Great Handguard

Looks great with my Criterion 13.9" barrel, the install process is a little weird but if you just follow their instructions it's really not hard. Seems sturdy so far as well, but I haven't really been pushing it in that department.
