Hi
My SniperM700 skins are finally ready. They are just the top layer, so you will have to add them as a layer to your original texture in Gimp/Photoshop. Also, there is much work to do if you want to turn them into working guns like in the image, but I've included step by step instructions for noobs. They are compressed as a .rar file.

[EDIT]
I realized that while I could not include stock media, I can include the .fpe files, and the folder structure, which will save you a lot of work. Just merge the "Files" folder for the individual guns with your "Files" folder.
