Respectfully requesting TACZ and Create: Immersive Tacz Integration guns. I did a bit of the legwork since I saw you constantly updating what you already have. (very greatly appreciated by the way)
Not sure if that's all that's needed to add TACZ compatibility to the gunner job but they'll hold them at least?

hope this helps!
