Complete A2 carbine Upper (16" barrel) Comes with spare double heat shield forearm. Less than 100 rounds through it. In great condition. (Was my spare) Since my rifle isnt selling and I need quick cash I thought Id give this a try as well. So whatever sells first. Otherwise BOTH ads will be running. Looking for $500 obo Its what I paid and I need cash, bad. Dicker if you will but flex room on the price is nil.. If you can get a cheaper upper elsewhere then do so.. I dont need to hear about it. It looks as every A2 carbine upper does.
