When player takes different stances (the ones that you can use to hide behind the cover, the weapon is shaking)

Use different stances. Look at the weapon
I'm quite sure it's an intended behavior to give the player a visual feedback of the less stability you have in those stances, which are not natural.
Infact if you look closer, you can notice the step lean left, that changes weapon shoulder too, shakes more than the others.
/downvoted for now, will upvote if a dev or a mod confirms it's a bug!
