Featuring a Patent Pending 2 Piece Barrel Nut that Provides 360 Degree Contact – Absolutely Lightweight and Super Easy Installation

Undoubtedly one of the leading brands in rail innovation and design, Fortis developed yet another spectacular handguard. The Night Rail™ is lightweight, very easy to install and is also able to mount with a full 360 degrees of contact. The new patent pending, two piece barrel nut is one of a kind! Developed from the ground up – the machining time it takes to make the barrel nut rivals the time making the actual rail. But wait, that’s not to say the rail is simple to make. One look and you’ll see that it’s designed to precision. As a result, the rail not only looks impeccable, but is still true to Fortis’s lightweight brand. The barrel nut/mounting system keeps the rail performing even during the harshest of conditions.
