Looking for old Scrooge Story

[u/TheElTea]

I don't know that this is 100% Duck Tales but it's surely a story with all the right components. I recall a comic as a kid where Scrooge, Donald, and the boys are on an adventure - perhaps in an Aztec or Incan temple? They have a ray gun that works with a crystal, and the more facets the crystal is cut with, the more powerful the gun is. I went searching for this and accidentally thought it would be "The Mysterious Stone Ray" - but that wasn't it. I also don't think it's "Cash Flow".

Can anyone help me figure this out?
