Never fired or even mounted on a lower. New in the plastic wrap; complete Colt upper. M4 w/14.5" barrel with step down and bayo lug, 1/7 twist, large diameter hand guards and removable handle. Everything is included and it's ready to mount on your lower, (carry handle, charging handle, and bolt/carrier). The person that I bought it from told me that it is an upper for the Colt model 6920, but I have been told that it actually would be a 6921; as the barrel length is 14.5".
