Fortis Manufacturing Rev II 15.3in M-LOK Free Float AR-15 Handguard Rail

Fortis Manufacturing’s REV II is a lightweight yet robust free-float handguard/rail system designed for AR-15 platforms. Built from a strong one-piece body, it helps reduce overall weight while maintaining rigidity for hard use. M-LOK slots at the 3, 6, and 9 o’clock positions provide modular accessory mounting, while the continuous top rail supports optics, sights, and other Picatinny-compatible accessories. The REV II features anti-rotation tabs for stability and a unique mounting system that attaches to a standard AR-15 barrel nut (not included) for straightforward installation. Compatible with both direct impingement and piston operating systems.
