Heyho,
I just reskinned the Hunting rifle parts i use if you want any other parts reskinned let me know.

You have to edit your Fallout4.ini

edit this line that it looks like this:
sResourceDataDirsFinal=STRINGS\, TEXTURES\

then just unrar and copy the files to your Fallout 4 directory.

Have fun and let me know if you have any issues.
