While I was at NTC AR15.com's Gunstruction had an update. They added AR10s to the mix. I downloaded the update for the app immediately and began building. I have shown this app and online program to several people I know. It is great for planning the next build (or four).
Here are some of the AR10s that I have built so far. Yes, I know. I have a thing for Rhodesian camo. It works really well in the desert environment that I currently reside in.
