Turret is very interesting.
Was studying it and found some peculiar things.

Lower part - good quality moulding..
Have looked if it is possible to install standard parts from HL or MATO.

The standard rotation ring from HL from ZTZ in general could be installed, but you will have to redo the wi-fi niche.

Airsoft gun body just is put to see how the main gun will look.

All the rest mechanisms: main gun elevation unit and recoil units will not be fixed there. Either you will have to re-work the turret.
