Forum:KB:Searching for a Certain Item

Alright, so, I've this vague memory of a weapon that I thought was used in something Star Wars related (a game or cartoon, I'm not quite sure) and it has been bugging me nonstop. It appears as these two tubes that are connected by cables(?) to a backpack(?), I'm confident that they fire concussion blasts but, as it is a vague memory, cannot be certain. If anyone has seen or heard of this item, please let me know; any information beyond "Yeah, that sounds familiar" will be helpful.
