FX King and Bottle

Hi all,

I have joined the forum as I can’t seemed to find an answer to this anywhere.

can anyone tell me if the FX King in Sub 12 with 500mm barrel can take a 580cc bottle.
I search the forum and found a pic of a 580cc bottle on a 500mm crown and it looks to have loads of room, but I can’t find any reference to the King. Pic attached

Can anyone help please?
