The Fortis Manufacturing Night Rail 14.4" free float M-LOK handguard is a lightweight, precision AR-15 rail system built for shooters who demand accurate, stable platforms without excess bulk. Designed around a free float design that isolates the barrel from the handguard itself, the Night Rail decouples harmonic vibration and eliminates contact-induced point-of-impact shifts—a critical feature for both long-range hunters and precision rifle competitors who need consistency shot to shot.
Installation is straightforward: the proprietary two-piece barrel nut design seats with 360-degree contact against the upper receiver, creating a rock-solid mounting foundation that requires no gunsmithing. Once mounted, you get a full-length Picatinny rail along the top for optics, laser, or secondary sighting systems, with additional short Picatinny sections at the 3, 6, and 9 o'clock positions for mounting lights, grips, or backup iron sights. The side and bottom flats feature M-LOK accessory slots, giving you flexible mounting options for everything from rail covers and cable management to tactical lights and PEQ devices.
At 14.4 inches, the Night Rail strikes a practical balance between sight radius and maneuverability, whether you're hunting from a stand, running a carbine course, or setting up a precision rifle at the bench. The black anodized finish stands up to outdoor use and integrates seamlessly with modern AR builds. This is a serious upgrade for anyone looking to tighten groups and eliminate handguard-induced accuracy variables without adding unnecessary weight to the gun.

Yes, the Night Rail is designed for standard AR-15 upper receivers and uses a proprietary barrel nut system that mounts with 360-degree contact.
A free float design eliminates contact between the handguard and barrel, which means barrel harmonics and shooter-induced pressure don't affect your point of impact. This results in more consistent, tighter groups, especially important for precision shooting and long-range hunting.
The full-length Picatinny top rail works with standard optics and sighting systems. The M-LOK slots accommodate any M-LOK-compatible accessories like lights, grips, and rail sections. Short Picatinny sections at 3, 6, and 9 o'clock will mount Picatinny-specific gear.
Fortis designed the Night Rail for straightforward installation using the proprietary two-piece barrel nut. Detailed instructions come with the handguard; if you're comfortable with basic AR maintenance, the job should be accessible.
