I use to have a problem with attachments in studio, and a lot of people asked me “Why are my attachments 10x bigger then my character”. The short answer is after a roblox studio update some user’s attachments scales were changed. If you haven’t fixed it here is how!
If you go to your model’s tab and go all the way over to the right you will see “Show Welds, Contraint Details…” etc. Next to all that is “Scale” and what mine and many peoples scale was set to was “57.98” or something around those lines when in reality it should be 1x.
If you don’t want the attachments at all simply click the “Contraint Details” box if it is darkened and it will make all the attachments disappear.
Hope this helped anyone with this problem!
