I ditched it out in the woods somewhere, hopefully no one will stumble across it...

I found a golden AKS in the pub in Elektro... I was unable to find a clear answer anywhere, but does anyone know if the golden AKS is legitimately obtainable, or am I risking being banned if I keep it? (I didn't know exactly where to post this as I am not sure if it is a glitch, cheat or just something rare, so please forgive me if this is posted in the incorrect location.) (Video proof: )
