ESB Blaster - flash tube

Hi everyone,

I did some searching and haven't found an answer to this question. Does anyone know far the flash tube should be sticking out of the Webley barrel?

I need to get at least an estimate on that measurement for something I'm working on.

Thanks,
GG

The actual barrel should be sticking out about 5 1/2" give or take 1/8". The front "barrel ring" will cover nearly 3/4" give or take 1/16".

Excellent - thank you very much for your help!
