Dear members,

It looks like ROTF Leader Class Optimus Prime won't have a gun like 2007 Movie Leader Class Optimus Prime had.

I was wondering, does anyone have any ideas what-so-ever on how to make a gun for ROTF Leader Class Optimus Prime? (Whether it's made from scratch or retooled from 2007 Movie Leader Class Optimus Prime's gun)
