Combine actors

Thanks for the reply. Let me clarify what i am trying to do. Lets say I had a barrell to a gun in my inventory and a body of a gun in my inventory. I want to be able to spawn both into the world, maybe on a table, and drag them onto each other. When they come in contact with each other the player can hit “c” to ‘craft’ a new gun. The two meshes would disaapear on crafting keypress and in their place a blueprint actor gun model that they can pick up into their inventory.
