The DPMS name has been dead for a while, well before the recent doings. Its not a huge loss, they didn't really do anything well, other than be needlessly weird.
I have a DPMS A2 upper and a DPMS lower that were made years apart and they fit like they were cut from the same piece of aluminum. They are mounted up with a 1/9 twist Armalite 16" mid length barrel and it shoots like a house on fire.
