SKU: FORTNTR-1
The Fortis Night Rail 556 M-Lok Black is a 14.4-inch free-floating rail system engineered for 5.56 NATO platforms seeking precision and modularity without added weight. Manufactured by Fortis Manufacturing, Inc., this M-Lok accessory rail delivers the structural rigidity and lightweight profile demanded by operators who require predictable accuracy across extended shooting sessions. The free-float design isolates the barrel from external contact points, eliminating harmonic distortion that can degrade shot grouping—a critical advantage in both tactical operations and competitive rifle disciplines.
Weighing 1.19 pounds and measuring 14.4 inches in length, the Night Rail integrates seamlessly with M-Lok-compatible handguards and upper receivers. The black hard-coat anodized finish resists corrosion and wear while maintaining a low-visibility profile. M-Lok slot spacing conforms to industry standards, enabling attachment of vertical grips, light mounts, slings, and other mission-specific accessories without rail-mounted concerns. The free-floating architecture preserves barrel harmonics throughout the firing cycle, supporting consistent velocity and bullet placement across varied ammunition loads and environmental conditions.
This rail suits precision-focused shooters, tactical marksmen, law enforcement specialists, and rifle competitors who prioritize accuracy over bulk. Whether mounted on a mid-length or rifle-length 556 platform, the Night Rail delivers the modular foundation necessary for evolving loadout requirements. Operators value the balance of structural support, weight efficiency, and compatibility that positions this system as a foundational upgrade for serious 556 builds.
The free-floating rail category has become standard in precision rifle builds because barrel isolation directly translates to tighter groups and improved shot-to-shot consistency. The Fortis Night Rail 556 M-Lok represents a proven, proven design philosophy that prioritizes accuracy potential without compromise on accessory mounting flexibility.
