How to use Paragon Weapons on other characters?

Hi, I retargeted every animations of other characters on Phase. Now, I want to be able to use their weapons. Swords were easy. I just took them from their models as a static mesh and reimported them to UE. But I don’t know how to use guns or bows, because they have bones.

To give an example, I want to use Sparrow’s bow on Phase but it has bones and stuff. If somebody could explain to me or show me a tutorial, that would be great.

Thanks in advance.
