[HELP] Broken Gear. How to fix it?

Hi guys.
few hours ago, I found a mistake in my gear, how to fix it?

Video:

Do all the Parts in the gun have the Massless checkbox checked off?

Yes.
I already tried to do this, nothing came of it.

Try turning off the CanCollide property on every part, and make sure nothing ever gets anchored.

I already tried to do this, unfortunately, this didn’t help either.

The problem is resolved. Issue is closed.
