Question Bone using the draw pose in unity

I don't really know how to word this question, but when i exported my gun from blender to unity the bone for the break-action part of the gun is using the draw pose. the rest of the bones are in the position it should be but the break-action bone is not for some reason
this is the draw pose, what the firing pose should look like, and what it is in unity:


how do i fix this?
