I suppose it may be possible to invent a Rube Goldberg machine with a rammer like AN-94 or Madsen. But doing so would defeat the purpose.

Not like AN-94 or Madsen are unreliable, but they were designed with complex feed systems from the outset, and it's completely different from retrofitting one of them into a pre-existing gun.
