Im new here.
Here's a picture of my cannon.

the black bit is the cannon and the white but under it is the barrel which screws on. I have a sprinkler valve on there. However im not using it electronicaly. Instead you have to turn that gear. When I get around to it I will attach some sort of a triger to the cog so that I dont need to hold it funny.
Any who, When I am shooting marbals out of there they tend to roll out when I aim down.
Is there anyway to stop this?
(Ohh and by the way heres a quick thing I made on Photo Shop to show you what I mean by the trigger. Thew only thing is my sprinkler valve takes a 1 quater turn to open. Hrmmm...
