Fortis Night Rail 5.56 Rail System - 10" M-LOK Handguard Model: 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.
