Fortis Manufacturing's REV II AR-15 M-LOK Handguard is an extremely lightweight yet robust free floating rail system. When designing the REV, Fortis didn't want just another rail system, they wanted a better, lighter, feature-rich handguard that was robust and within budget. Fortis managed to reduce as much weight as possible while maintaining strength by utilizing a 1-piece body design. M-LOK cutouts are added to the 3, 6, and 9 o'clock positions for modularity and additional weight savings. The REV II's unique mounting system attaches to a standard AR-15 barrel nut (not included) for quick and easy installation. The REV II is compatible with both direct impingement and piston operating systems, and features anti-rotation tabs for added stability. Barrel nut not included.
