Guncam? Please help

[OhMargott]

Hello guys how are you? I have a question. I know it's possible to have a guncam view because I've seen videos, but I can't seem to find it. Does anyone know how to do it or has a link to a thread about this? Thank you, and if you're interested in watching COD vids you can check ouy my channel:

I haven't spread the word because my videos aren't really good yet. I need to improve a lot, but feel free to check them out and see what you think
