These P&S 11 rib rail covers come in both new and used condition. Used covers have some obvious wear from previous use. However, they are still in very good condition and guaranteed to be fully functional.
The lightweight polymer panels are ribbed for an enhanced grip. Also, they insulate your support hand from barrel heat. While originally designed for use on the Knights Armament Company (KAC) M4 RIS and M4 RAS rails, these panels are also compatible with many other railed handguards.
