The KAC Keymod Flat Panel Kit includes a set of 2 - 5.5” polymer rail panels and one short switch pocket. Each textured panel snaps securely to any bare section of Keymod equipped rail, providing a more positive gripping surface and also insulating the support hand from barrel heat. The long panels have 3 cable channels to help with switch cable routing. These rail panels are very thin adding almost no width to the handguard. While designed for the URX 4 rail, these panels will also fit any other rifle handguard that has a Keymod interface.
