Minimap Script mess up gun?

I made a gun model and welded it together then test dropped it to make sure it worked. Then when I inserted a minimap script into my model and got the holdable version the pieces would be in the center unwelded and the character would only be holding the handle. I named all the parts to weld again (so it was as well welded as the giant model but no effect). Its weird because the character no matter where he walks around the parts (again except the handle) always go to the middle of the baseplate no matter where the character is.
