FIGURED IT OUT.
All the parts for a weapon are stored on one model, represented here by different colors.
I believe you just need to disassemble faces of the model until you find what you want at worst case scenario. I've looked for a while now and I don't see any other way to "separate" these models. Here's the file in FBX format if you want to look it over.
