All I'm waiting on is my hand guard. Then it will go something like MI barrel nut -> gas block/tube -> weld/pin compensator -> hand guard. all that waiting for one freaking specialty barrel nut.
I didn't run into too many issues with assembly, although the DPMS takedown pins are tight as hell. It took some oil and elbow grease to get them to the point where they're removable without a punch.
