CS:GO weapon scope view position
 

I created a custom model for weapon_aug, the scope is a little shifted to the left side and in game when zoom in, I can see nothing, because the view point sets somewhere in the muzzle.

I updated the "unzoom" attachment point in the model to the right position, but the zoom view position hasn't changed. I thought, there should be some datamap property or netprop, but I can't find it, is it hardcoded?, or still I can change it from my server?
