Why does the Motor6D only shows on the Client Side and not also Server Side?

So it's a drill tool so when you press a key it switches stances, it works fine, animations are good, no errors. But the position of the gun, it only shows on the Client and not also the Server, does anyone know why?

This is what is inside the tool: https://media.discordapp.net/attachments/462676564815904768/840644481279197244/unknown.png
