I’ve built four of these ‘M16A4’ types. For the hand guard I used the P&S Products manufactured quad rail system (Cage Code) model 4U486 (I had some of these I picked up surplus for $30.00 each with some other stuff – its the Knights Armament M5 Rifle RAS Forend Assembly but manufactured by/through P&S Products that were used to fill the same contract during the GWOT). Oddly enough, its this hand guard that prompted me to want to build the ‘M16A4’ types.

you could have just typed larue.
it’s good to know that the slower twist was able to stabilize the heavier projectiles, however what about a 1:9 leads you to greater weight?

All these many decades later, every time I break down an AR for a deep clean or parts replacement, it feels like one of my DI’s at Ft. Ord is looking over my shoulder, making sure I do it right.
