The Fortis Switch Rail Mod 1 (brand part no. 556-SWITCH-M1-138-ML) is a 13.8-inch, free-float M-LOK handguard that takes the original Switch Series design and tailors it specifically to shooters’ most requested features. M-LOK slots run the front section of the rail so lights and other accessories mount directly without needing an offset mount, and the 13.8-inch length is intentional: it is sized to leave only a minimal gap when paired with most direct-thread suppressors on a 14.5-inch barrel. The rail uses a patent-pending locking mechanism that lets shooters remove and swap the rail without tools, a feature Fortis built the whole Switch platform around. Despite the added functionality, the handguard remains extremely lightweight for its length, adding minimal weight to the completed rifle.
