My opinion is that CTD is a DBag company that I will no longer deal with. Many folks will echo that sentiment.
Mossberg's version of a complete entry level AR15 does generally measure up pretty well within that market (vs DPMS, DelTon, etc). It's an okay buy for $500-675. For any more, you'll be far better served with a PSA build. An $800 PSA will arguably net you $200-500 worth (over most $600-800 big box store entry level ARs) of parts upgrades depending on the deal you jump on.
