When the the weapon is at rest/hip level/out of the aim position etc it vibrates and jumps around.

see video example below:
I think this was added in to show that your not in a comfortable position.When you press stand up or crouch its not shaking but if you then adjust to the lower or high stand crouch positions the weapon shakes slightly.
If that is correct wolfstriked it looks horrible and needs removing. As you say it does it in all Adjusted stances but is ok in normal stand, crouch, prone.
Quick video of a Standard BLUFOR rifleman droppped in the editor a rotating through different stances. http://youtu.be/TT04St8Ujp0
Its almost like the animation is speed up, although crouch does not shake as such the gun wobble is definately faster than standing
