These Knights Armament Company (KAC) 11 rib rail covers come in both new and used condition. Used means the rail covers have some obvious wear from previous use but are still in very good condition and guaranteed to be fully functional.

The lightweight polymer panels are ribbed for an enhanced grip, and help insulate the support hand from barrel heat. While originally designed for use on the KAC M4 RIS and M4 RAS rails, these panels are also compatible with many other railed handguards.

    Very pleased with an awesome product, and amazing customer too. Thank you. Best rail covers on the market.

  2. Alex K. (verified owner)

    Fantastic price and product. Ordered two of these, they arrived quickly and were in good condition. The hand-written thank you was definitely appreciated.

    One quick tip for purchasers- if the rail covers are not locking on and sliding around freely, just put a screwdriver tip through the clip on the outside of the rail and pull gently. That pulls everything tighter and should lock the cover into a rail slot.
