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.
Don't know about that after the last panic AR prices hit the floor and I picked up a new in the box DPMS Oracle model for $450 .It works perfectly and the gas block was picatinnied on the top for my laser and the flattop picatinny hosts a red dot sight it is my low- no-any light shtf rifle. Nothing that costs more is anymore reliable. Mb
