The PTS Fortis rail system is rugged, lightweight, free-float rail system for most airsoft M4 guns setups. The PTS Fortis offers 12" of continuous 1913 mil-spec picatinny rail along the top of the rifle that feels and looks like a completely monolithic (one piece) upper.
The PTS Fortis 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.
