These Knights Armament Company (KAC) 6 rib rail covers come in new and used conditions. Used means that they have some wear from previous use.

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.

    I was making a clone of the rifle issued to me while I was in the Army, and was looking for some Knights armament rail covers to complete it, and the few places I did find them online were charging something like 26 dollars for 1 rib panel, which I thought was utter lunacy. In my poking around online I came across Venture surplus, decided to look and see what I could find, and here they were, used rib panels at a very reasonable price, and real Knights Armament, not some weird knock-off like you’d find on Wish or some such site. ordered nine of the 6 rib rail covers, and they showed up in my mail in less than a week. The condition they are in is great, I’d say out of the nine rail covers at least 6 of them were in new or like-new condition, the rest being just used enough to give them some character while not at all impacting their quality. Which to my way of thinking is a bonus, because it saves me the time and effort of artificially aging them so they look like my old service rifle. 😛 All in all, in my pinion these are a great get for the money, and I honestly wish I had looked at Venture Surplus much earlier in my build process.
