Hi all- I just purchased a lower which I am making complete soon, so i am in the market for a complete upper. I would prefer something inexpensive, and don't care very much about the feature set. Does anyone have an upper they upgraded and have nothing to do with? Let me know! I would prefer it to be 100% complete, however I am willing to buy as minimum as a barreled upper. Please let me know what you have, and which parts would be required to make it 100% Thanks.
