Knights Armament Rib Rail Panel
The iconic Knights Armament rib rail panel has seen use all over the globe on US military M4 Carbines. The lightweight polymer panels have ribs for an enhanced grip, and help insulate the support hand from barrel heat. Designed for use on the KAC M4 RIS and M4 RAS rails, as well as the KAC M5 RAS rail.
Please note, these rail panels are from different years, and may or may not have the cage code molded into the rail.

I had ordered two new 11 rib covers, the very next day i was informed they where out of stock and could cancel or send me the surplus rails. I chose to have the surplus rails sent to me as well as a slight refund, they where very fast in replying to me as well as getting the product shipped. I look forward to doing business with them again.

These are genuine KAC rail covers. The “1S002” cage code is not there but according to Knight’s Armament, these are military-issued. Great price! You can’t beat ’em.

Thank you for your feedback! Some of the rail covers do have the KAC cage, but others do not. We hope that you’ll shop with us again! – MOD Armory customer service

COMPATIBLE WITH AUTHENTIC KNIGHT’S ARMAMENT RAILS ONLY!
Purchased a 2-rib rail cover, new for $20 shipped. Very deceptive product and product description: “…these panels are compatible with other handguards with MIL-STD-1913 rail systems.” Not true; more accurate to say these panels fit AROUND any MIL-STD-1913 rail system but ONLY lock into an authentic Knight’s Armament Company rail system.
If your rail is not an authentic KAC rail, these panels will slide onto the rails but not lock into place. Therefore these rail panels slide around uselessly on non-KAC rails. However, authentic KAC rails ($250 apiece new) have additional milling cut into them specifically for their proprietary rail covers. Look it up… wish I did.
