The real deal - Knight's Armament M5 Rifle RAS Forend Assembly with Three 11-Rib Panels

This is the real deal that the U.S. military uses. According to my son, this is the rail system his M16 had. So it's perfect for that military rifle build. In addition to being the real deal, it's also the best rail system I've ever had. Follow the instructions and it installs smooth and easy, and is the most solid rail fore stock I've seen. No flimsy rail for bipod, my bipod is solid as a rock. Comes with plenty of covers for the unused areas. While being solid, it has less bulk than any other rail system I've had which helps the rifle to fit in the safe taking less space. Plenty of rail to install all the accessories you could ever want, or could carry. Absolutely the best rail system. And a far cry from the triangular hand guards of my day :^) I highly recommend it.
