This is a one time purchase, and yes it's your very own exclusive gun. Purchase a custom gun to get your own model of a weapon imported providing it isn't in Aurora already. You can find guns on many different sites (GTA5Mods, GTAInside etc) and also from certain Aurora players. After purchase, please directly message "Message Staff Here" in the Aurora Community Hub Discord and send the Tebex transaction ID and the link to the weapon model. We'll take care of the rest.
