Fortis set out to design a rail that was better and lighter, rich in features, robust and affordable. The result was the REV free float rail system. Its weight has been reduced as much as possible without sacrificing strength by utilizing a one piece body design. KeyMods are on the 3 and 9 o'clock positions for modularity and additional weight savings. The mounting system captures a standard AR-15 barrel nut.
