HI PraisinBran. Thank you for your reply. I think I'll go with the creative way. Thanks for the suggestion!
Thank you for the reply. I am just wondering what it means to cutoff the supply line when you fire? I am new to homemade and modding, sorry about that.
The answer to this question depends on whether you are using a pump as your pressure source, or a reservoir. If you're just using a pump then you can use almost anything because you don't have to cutoff your supply line when you fire.
Directional control valves (3-port)
Push-button valves (2-port or more)
Slide valves (you may want to add a spring return)
Blowguns (you can buy these with a pistol grip)
And more will all work
