For those looking for a 22LR upper Midway has some of the DPMS ones in stock:
DPMS AR-15 A3 Flat-Top Conversion Upper Assembly 22 Long Rifle 1 16
I believe these are based on the Nordic Components bolt design also utilized by JP enterprises. NC's have been unobtanium for 18+ months so this is about as close as you may get for the near future.
