Trying to rename ar2

Bassicly iam trying to change the entity name of ar2 so when picked it up it says something else instead of Ar2 or Pulse ammo anyone know how to this?

yeah, you make a dummy lua swep that just removes itself and silently gives you the ar2 when picked up
then you can call it ass balls dildo gun or whatever you want

look up SWEP:Deploy(), ply:Give() etc
alternative you could detour the function that shows what you picked up on screen and change the text to whatever if its pulse rifle or pulse rifle ammo
edit: see gamemodes/base/cl_hudpickup.lua

Cant someone just go to the ar2 itemfile and change its name :o?
