I have a customized Verminator with a 400 cc bottle on the front that developed a slow leak. Took it out of the custom royale stock and check fill fitting, gauge, and bottle connections etc. with soapy water. Could not see any bubbles. Is there anywhere else it could be leaking? Where do these thing generally leak from? Thanks to all. Picture of it below.

Have you or do you know if the verminator can be used as a pistol ?

I'm sure it could be, but I think it would look funny with a 400cc bottle in front.
