M16A3

I have been considering an M16A3 clone build. The only part i am unclear on is, what quad rail handguard did they use?

The quad rail handguards were/are made by Knight's Armament Corp..

My Marine Sgt. Nephew carried an M16A3 "Musket" in Afghanistan. He preferred it to thesexy M4s his troops had because he could actually reach out and hit bad Mujahadin at 300 yards and and make them good Mujahadin. He was a true Marine Rifleman in every sense of the word. After several tours, he ETS and went to work for the local Police Department.

Rail adaptive system M-5 ?

Ok. I mis spoke. It is the M5 rail on the M16A4. I guess the A3 had regular handguards. Either way. Thanks everyone!
