The Fortis Rev II M-LOK Handguard, sold here in a 9.6-inch length (brand part no. REV-II-9-ML-BLK), is an extremely lightweight yet robust free-floating rail system. Fortis Manufacturing built the Rev II around a one-piece body design to reduce weight while maintaining strength, with M-LOK cutouts at the 3, 6, and 9 o’clock positions for modularity and further weight savings. Its mounting system captures a standard AR-15 barrel nut for easy installation, and it is compatible with piston-driven uppers as well as standard direct impingement systems. Anti-rotation tabs keep the rail from working loose under recoil.
