The Fortis Rev II M-LOK Handguard, sold here in a 6.7-inch length (brand part no. REV-II-7-ML), is an extremely lightweight yet robust free-floating rail system. Fortis Manufacturing built the Rev II around a one-piece body design specifically to reduce weight while maintaining strength, rather than just chasing a lighter number on paper. M-LOK cutouts sit at the 3, 6, and 9 o’clock positions for modularity and further weight savings. Its unique mounting system attaches directly to a standard AR-15 barrel nut, which is not included, for quick and easy installation, and it is compatible with both direct impingement and piston operating systems. Anti-rotation tabs add stability under recoil.
