Need some assistance

So, I got a weapon reskin from the workshop, and people said it was good, so I tried it out. I didn’t like it, so I deleted it, and now I don’t have any weapon models. Can someone give me the original weapon models or perhaps a good model pack and some installation instructions?

Thanks in advance!

Well, erhm, quick change, now half of the textures are missing. A bit of help?
