Editing the viewmodel / hands FOV of a mod weapon?

[Curratum]

I searched high and low with Google, but you can imagine "fov mod weapon" and any combination of those is a nightmare.

 

I'm basically trying to do a personal edit of a modded weapon. I really love the gun, but its default viewmodel and player hands in first person are much more zoomed out / higher FOV than the rest of the vanilla game guns, and it looks jarring, I can see a huge portion of the rifle's stock in my view etc.

 

I tried my best to find a way to edit the individual weapon mod and change the modded weapon's first person FOV but I could not find a way.

 

Any help will be much appreciated!
