Gunsight arg mod trough skin

[paco2002]

Hello!

This might be a bit technical, but I will try to make it clear. I've been trying to remove the gunsight (without removing weapons) to see better. 

Trough model viewer, I found that the argument is 926, but I made custom skins to modify it the same way you modify external models, but I had no luck with it, so I kindly ask if someone can help a bit with this.

I add a couple of photos to help understanding.

In case someone is wondering why I want it to make it trough a livery is because I mainly play dynamic servers, and the only way of modifying this things are trough livery.

Thanks!nullnull
