Please help identify this Ausini piece The one that looks like a rocket head or a projectile tip. I hoped there was a corresponding LEGO piece. There is no inventory on the instructions.
Even though there's no corresponding LEGO piece, you could get away with this substitution:

 

Part #89522 - Horn (Unicorn).

This is how it would look with the pieces you have, and color wise the Horn comes in metallic silver too.
