BO3 PaP Weapons when bought Hello and sorry if I had violated any rules during this lost.

I was wondering how so many videos showcase the player purchasing any wall weapon or just receiving a weapon in general and it automatically comes pack a punched? It is related to a gobble gum or defeating a easter egg? 

I’ve tried using google but phrasing the question is quite difficult. 

I’m also specifically trying to accomplish this on origins of it matters.
