Some tank sights incorrectly follow turret movement in VR

[some1]

I noticed that the main gun sight view in M4A2 and the roof sight view in T-34 and KV-1 tanks behave as if the gunner was sitting in the hull and not in the turret. Meaning, that if rotate the turret 90 degrees to the right, i also have to rotate my head 90 degrees to see the sight. Which is obviously incorrect, as the gunner rotated with the turret, so he had the sight right in front of him all the time. 

 

In 2D mode all sights work correctly, this is only an issue in VR.
