Brand: Fortis Manufacturing
Night™ Series

When designing the Night Rail™, we wanted to design a handguard that was easy to install, but also to be able to mount with a full 360 degrees of contact. Our new patent pending, two piece barrel nut is one of a kind. We developed it from the ground up and the machining time it takes to make the barrel nut, rivals the time making the actual rail. That’s not to say the rail is simple to make. One look and you’ll see that we really took time with this in design and development. What we 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.

Being one of the leaders in the industry of rail innovation and design, it’s always a challenge to innovate new products that function well, but look great also. We’re up for the challenge with the next chapter of our product line – the Night™ Series. I think you’ll agree that we hit a home run with the Night Rail™.
