Fortis REV is an extremely lightweight yet robust free floating rail system. The REV has managed to reduce as much weight as possible while maintaining strength by utilizing a 1 piece body design. KeyMods were added at the 6 & 9 o'clock positions for modularity and additional weight savings. Its unique mounting system captures a standard AR15 barrel nut for easy installation. Because of the anti-rotational tabs, the REV rail may not fit all uppers without slight modification. Fits most mil-spec forged uppers without any issues.
