The Fortis Night™ 10.5” Rail System is where precision engineering meets lightweight performance. Designed for AR-15 platforms chambered in 5.56, this free float M-LOK handguard is built to enhance control, accuracy, and durability — without adding unnecessary weight to your rifle.
Fortis set out to design a rail that installs easily yet locks up with absolute stability. The result is the patent-pending two-piece barrel nut system, a breakthrough in rail mounting technology. It provides a full 360° contact surface, distributing pressure evenly for rock-solid performance. This means your rail stays tight, your optics stay zeroed, and your rifle stays mission-ready no matter the conditions.
Whether you’re upgrading your duty rifle, building a lightweight SBR, or fine-tuning a competition setup, the Fortis Night 10.5” Rail offers the perfect balance of strength, style, and performance.
