After I made this I thought it would be cool to add prefixes. You can't write professional on it or plate it with gold, but what you can do is add a manual killstreak kit. It is called a 5 to 5 counter ( means that I am not good enough and it counts first 5 kills, next 5 kills and so on to 20 ) and you have to rotate it manually. And not cheat ;D ). I inspired from a password lock, where you rotate numbers but I made my own counter.
Hope you like it!
