Value of AR Upper

[Superman]

I have a 20" upper that I would like to sell, but I don't know what it would be worth. I got it in a trade a while back. It is supposedly a Colt upper. It has a flat top with a rail on the reciever and a smooth round free float tube, forward assist, brass deflecter, and iit doesn't have a dust cover on it.

The only markings I can find is on the barrel C MP 556 Nato 1/7. And there is a D stamped in the bolt.

So what would this be worth to someone?Probably has 400-500 rounds through it.

The bolt is a DPMS, almost impossible to tell a flattop from just the few markings available. The keyhole marking that is on it probably is generic to several brands.

The only real way to tell a Colt upper is on the full-carry handle ones for the most part. It looks like it should have a tear-drop shaped forward assist in the picture, so it might be Colt but unsure. It looks like it should have a dust cover on it since it looks like the holes are there for the retaining pin, but hard to tell from the picture.

The barrel is a post-ban Colt barrel. I have never seen a Colt factory gun with a free float tube or that type of gas block.

The upper in short is a frankengun mixmaster. Worth about $165-$195 without the BCG/CH & the dust cover assembly, add $100 if you include the BCG/CH.
