Well I recently figured out how to use weapon skins on CS:S and I found this really cool skin for the AWP. I took a demo of me using it and getting a headshot. Click to download! Download and drop in your cstrike folder. i forgot what to do after... hehe.
they have it in youtube if you type "magic bullet css skin" interesting a lil bullet floating above your finger.
i've used that skin for a while its pretty badass. try and get a noscope headshot with it, then you'll truly be 133t. also try the other finger weapons : Poke finger (knife), Finger TMP, Finger Scout, Finger dualies (search these all on FPSbanana.com) the reload on the dualies is scary though and you'll want to delete the sound worth a try though. i think they will be your new favorites.
