SOLD I have a COLT A2 Upper Receiver for sale. Great condition. It includes the following: Forward asssist, port door, A2 rear sight. There is marking's on the carry handle near the rear sight of "CM". There is no bolt or barrell with this assembly. It was removed from a pre-ban Colt sporter match HBAR. The receiver has the SMALL forward hole. I had ADCO replace it for me with an A4. He thought I could get around $200 for it, but this is nagotiable.
