This modification lets you use "80's Calling" Upper Receiver' textures even with custom colors/weapon skins applied.
It'd fit the SPMS mod nicely, but I understand that some people would like to use this receiver purely for the stats, so I decided to make this mod standalone.
If you want lower parts of the receiver to be paintable, just remove wpn_fps_smg_cobray_body_lower_jacket_cc.material_config and wpn_fps_smg_cobray_body_lower_jacket_cc_thq.material_config from the mod.
