We rescued several Armaliite uppers from DOE, the barrels were not apart of the uppers. ( They had pitting inside the rifling)

So for this build we used the following parts from that armalite upper rescue. All were from a complete upper minus the barrel.

Square forge marked receiver (came off of an armalite factory rifle).

Armalite BCG

NEW Colt 10.3″ 5.56 Barrel.

NEW Colt Delta ring assembly.

NEW Colt Gas tube & FSP.

New take off skinny carbine round 7 hold Hand Guard.

Armalite Birdcage muzzle device.

This upper is complete minus a charging handle.
