Exporting an fbx reload animation correctly?

Last time I exported an animation from blender to unity it had a ton of problems.
In first person-

This is the way I do it-

export the entire thing- rig+mesh's

for instance- the armsmesh+rig+weapon mesh+clip mesh

I have tons of problems when doing this.


Is there a simplar way to exporting a full reload animation to unity from blender using .fbx



The whole goal is too have a simple reload animation that uses the arms and mesh of the weapon and clip to work.

ps I tried searching but nothing gives me a good answer.
