Why Choose the Fortis Night™ Rail System

The Fortis Night Rail isn’t just designed for aesthetics — it’s engineered for performance. The free float system ensures your barrel operates independently of the rail, allowing for greater accuracy and improved heat dissipation.

Its two-piece barrel nut sets a new standard for installation ease and mechanical strength. Unlike conventional designs, this system locks your rail down evenly, eliminating the chance of rotation or misalignment over time.

Whether you’re running your rifle in competition, tactical training, or precision shooting, the Fortis Night Rail provides unmatched stability and confidence shot after shot.

Technical Specifications

Installation & Compatibility

The Fortis Night Rail comes ready to install with our proprietary two-piece barrel nut and mounting hardware. No gunsmithing required — if you can torque a standard barrel nut, you can mount this rail in minutes.

Compatible with all standard AR-15 5.56 platforms, this rail provides full-length coverage for 16-inch barrels and is ideal for mid-length or rifle-length gas systems.

For optimal performance, Fortis recommends pairing the Night Rail with their low-profile gas block and barrel nut wrench (available separately).
