If you find a typo keep it for yourself :P
First off I show you the skin without changing anything.
Now the tutorial begins, you go to:
C:\Program Files (x86)\Steam\SteamApps\common\Counter-Strike Global Offensive\csgo\scripts\items
Backup the items_game.txt
Download Notepad++ and go to line 27154 to search your weapon from the collection its from.
Copy the text left from the weapon name.
Press CTRL+F and search your weapon, press enter often times till you see ""name" etc",
remember or write down the number in the left above "name".
Go to line 27154 again and look for a weapon you want to replace your weapon with e.g the cyrex.
Copy the whole code and go to the number you wrote down and replace everything.
Save the file and start your CS:GO, your weapon skin should be replaced!
If you have any problems comment down below and I'll try to help you! :D
