I know this is a little more than you wanted to spend, but I have a Colt (CM forge mark) A2 Upper Receiver I will sell. It is a small hole (mil-spec) upper. Rear Sight Assembly, Forward Assist and Ejection Port Cover are included. Exterior finish has a few rub marks, but looks very good overall. Interior looks good except for some scratches where the barrel extension would sit. Looks like someone tried to push a barrel with a burr on it into the receiver and scratched it as it went in. You will never see this area once you install a barrel. Sounds worse than it looks, but I don’t want you to be surprised. Price is $100.00 shipped. Let me know if you're interested.
