Odd gun, another repaint? It has a 12-dart normal clip instead of the standard 18-glow-in-the-dark-firefly-clip and 25 yellow (?!) darts. Seems to be an Elite and thus probably has the same technique as the normal Elite Rayven. Why they'd make another repaint, earlier in green, blue and now bee-yellow is not clear to me. I can't imagine anyone asking for a yellow Rayven, or Hasbro just had too much paint left from the old N-Strike guns. Another possible solution might be a completely new sub-line of Elite, hence the new darts, also yellow.
So far it's only being sold on amazon.com by a third-party seller called AR-DISCOUNT at the price of 29.99$.
