Those are call of duty files, not much cod models on there so you just happened to pick a wrong one .. sorry . You can see it's the right kind of file if you download it and the package has a 'materials' and 'models' folder (and usually some more folders).
Well my bad thanks for trying, but as at the moment there is nothing I want but, I will come back to you when I need something, and that sniper, you linked me, that you made is awesome.
But thank you for the help and the awesome skin.
Keep up good work.
