The Fortis SWITCH Rail in 15.3-inch M-LOK Mod 1 (Fortis Manufacturing part no. 556-SWITCH-M1-153-ML) is an extremely lightweight, free-float AR-15 rail built for shooters who want to swap handguards between mission or competition setups without tearing down the whole upper. Fortis Manufacturing engineered the SWITCH around a patent-pending locking mechanism that allows tool-less removal, so changing rail configurations takes seconds instead of a full re-zero session. It keeps the same robust, free-float construction as Fortis’s other rail lines while adding that quick-change capability. It is a strong fit for anyone running multiple configurations on the same rifle.
