PTS FTS Fortis REV Free Float Rail 12'' Flat Dark Earth





The Fortis REV™ II rail system is rugged, lightweight, free-float rail system for most airsoft M4 guns setups. The REV™ II rail is installed with a standard barrel nut and offers 12-inches of continuous 1913 mil-spec Picatinny rail along the top of the rifle that feels and looks like a completely monolithic (one piece) upper. Anti-rotation tabs integrated into the inside diameter of the rail system ensures that the rail stays locked in position and contributes to the rifle’s rigidity.

The REV® II M-LOK® features the Magpul M-LOK® mounting system, a modular rail system that decreases overall gun weight and increases customizability. The M-LOK® is utilized on the 3, 6, and 9 o’clock positions and runs down almost the entire length of the rail, allowing the user to attach an abundance of lights, grips, rail sections, and all other M-LOK® accessories. There are also four rotation limited QD sockets at the front and rear of the rail at the 3 and 9 o’clock positions to allow for the usage of a 2-point sling.
