I have sold several of the Diamondback DB-10's , both in the 16" and 18" barrel lengths. I have also kept in contact with the customers who purchased them for feedback. Every single customer, with many also owning other AR-10's, have had nothing but good things to say about them, including customers who wished they would have bought more than one given the price at the time. I know such a small group isn't representative of the entire line, but the feedback has been awesome.
