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 this 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 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, and 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 homerun with the Night Rail™.

Highly recommend.Review by Greg
Very well made and light weight. Excellent products and would highly recommend it. This rail does not have the full top rail like the Fortis but does offer a less bulky appeal and if you don't need the full rail then this is what you need. (Posted on 8/21/2016)
