Can a TM M4 SOPMOD have a HPA or Polarstar conversion and still retain its bolt lock and recoil attributes

Hi im reasonably new to playing airsoft but have been folowing the sport for a very long time im getting my UKARA soon and was just wondering if i can get a M4 SOPMOD but install a Polarstar later on into the rifle and have it retain its SOPMOD values?

No, the polar star system replaces the entire gearbox.
