Why Shooters Choose the Fortis Night Rail

The Night Rail Series represents a new era of innovation for AR-15 builders. It’s not just about shaving weight—it’s about achieving balance, control, and reliability without compromise.

The proprietary two-piece barrel nut locks the rail down evenly, preventing rotation and maintaining alignment even during heavy use. This level of rigidity gives you consistent performance, whether you’re zeroing optics or running drills at the range.

Pair that with a slim, ergonomic profile and sleek machining, and you’ve got one of the most advanced rails ever made for the AR-15 platform.
