Conseguir imagen de perfil de pistola

Como se consigue imagen de perfil de dos pistolas q vi en algunos jugadores?

I am sorry, I don’t understand. Would you please edit this and add a English translation?

How can you get a profile picture of guns I saw in some players?

You mean this?

You get those as a prize if you win against a developer of the game during the special Devastation events that happen every now and then.

Thanks for answering
