Fortis Night Rail 12.9" Keymod

When designing the Night Rail, Fortis wanted to design a handguard that was easy to install, but also to be able to mount with a full 360 degrees of contact. Their 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. Thats not to say the rail is simple to make. One look and youll see that they really took time with this in design and development. What they ended up with is a rail that not only looks amazing, but is still true to Fortis lightweight brand. The barrel nut/mounting system keeps the rail performing even during the harshest of conditions.
