This Keymod Rail Panel kit is made to fit all KeyMod mounting surfaces with seven consecutive KeyMod Slots. It has a ultra-slim and radiused surface which allows a "round" handguard feeling, from an octagonal profile, aggressive non-slip or non-reflective surface, and is ventilated for cooling. Included is a bi-directional locking tabs on either end, depending which direction they are installed and five matching color KeyMod panel strips.
