Remember when stock weapons used to look 'just great'? Back in 2013, for example, especially the metallic ones; all they had an unique, TF2-ish style. All that changed on 2015's "Gun Mettle" update, which made them look even worse.
This mod is intended to bring back the fashion to these weapons (the ones that got officially converted to use the "c_models" system). Check out the screenshots and the video's description to learn more about it!
