I have a what I believe to be a complete Colt barreled upper. The 20" barrel is marked C-MP Chrome Bore and gunsmith who put it together informes me that the upper and barrel is Colt. The lower is DoubleStar and I want to rebuild using a flattop upper and 16" barrel. Any suggestions on the best place to sell my upper?

The EE is an excellent place to sell your gear. But, I'd really rethink selling it. You have a GREAT piece of hardware there that you are going to essentially give away just because it's not 'in style' at the moment. Have you really not thought about keeping it? I love my carbines... but I really love my rifles too...

I'd agree with the 'keep it' vote. That barrel is a great piece and you should hang on to it for a future project.

Price on these varies but if condition is good or better and upper is clearly Colt proof tested figure it's easily worth more than a flat top with 16" barrel of most any mfg besides Colt or top tier model. A Colt 6920 upper and probably even a 6520 is worth considerably more than a surplus 20" rifle upper in today's market due to demand and original costs. Check the EE for a price comparison and see what's selling for how much. Lot of that stuff gets negotiated also.

If all I wanted was a good shooting flat top with 16" barrel and didn't need a Colt think I'd just build one and keep the Colt. Flat top receivers and barrels are cheap right now. Site vendor DSA has some real deals and so does vendor PSA. PSA has a broad range of stuff from low to top tier. DSA is probably gonna be more towards the lower tier but we are talking AR-15's. Even low tier in many instances are mfg'd to same milspec and shoot as good or better than top tier. Take two identical models from any mfg and one will shoot better than the other.

If you want a Colt flat top 16" upper expect to pay as much as $200 more than the competition but it will be all Colt and in many instances worth it. Depends on what flavor carbine you really want. Most all my homebrewed carbines will hang with my Colt 6520 for accuracy and a couple are actually better with light bullets. With heavy bullets the 6520 is better at longer ranges but also has a faster twist rate. Simple justification for having a few different flavors and ice cream comes in different flavors for a reason.
