need help making a new weapon mod

[XM1V1]

I have a wip blender model that combines a syringer and a mr handy arm with the handy mini flamer to make a flamer rifle but I need help getting it functional, at the time of writing, I have the handy arm affixed to the syringer receiver but I do not know how I'm going to attach a flamer tank for a reloadable magazine or what reload animations I'd have to use, or how to apply a reload animation (this is my first time making a standalone weapon mod)

 

attached is a screenshot of the model I have so far

 

any help or advice is appreciated thanks
