My CAR15/654/SP1 Carbine clone...
I almost had it right with my USAF Franken Carbine build, but it had an M4 barrel. The Holy Grail for a CAR build is the 6420/6720 1/7" twist, 16" Pencil barrel...which I finally found. The below project is what was left after I took my retro 602 and a Carbine build, when I sold off all the 20" barreled retro stuff. Total weight empty is 5 pounds, 7 ounces!
Colt 604 early square forge upper
Colt 6720 1/7 Pencil barrel
Colt 601 Chrome BCG
Colt Fiberlite stock set
Nodak Spud 601 lower
Kalifornication compliant bullet button and Colt 20 rounder blocked to 10 rounds.
