Editing first person model positioning for a weapon

[GTVel]

So i'm trying to create a weapon, and i've come to the issue where the model is having some major clipping issues in first person. The model isn't positioned exactly the way I want it.

 

What I initially tried to do to fix it, is copy and paste the original nif file and adjust the position in nifskope for the first person file. Only issue is that it changed both the third person AND first person positioning.

 

Any help would be greatly appreciated.
