Will this fit a stand lower, e.g Aero Precision M4 or Noreen AR-15? I know it will require mag adapter and unique mags to function, but will it fit? Expert Answer

The CMMG Mk10 10mm Banshee Upper Group Receiver will be compatible with Milspec AR15 lower receivers. However, you will need to use an adapter that allows you to run Glock 10mm pattern magazines in order for it to function.
