Fortis Manufacturing produces premium, lightweight AR accessories focused on strength-to-weight and ergonomics. Key products include free-float handguards (M-LOK), muzzle devices (RED/Control), charging handles, gas blocks, and rails. Fortis parts work with standard AR-15 and AR-10 platforms: upper receivers, barrels, low-profile gas blocks/tubes, muzzle threads (1/2×28, 5/8×24), bolt carrier groups, charging handles, and Picatinny/M-LOK-mounted accessories. Ideal for builders seeking rigid, low-weight components for tactical, competition, or duty rifles without sacrificing durability or compatibility.
