Use the Zero Silencer, and the silencer's ID should be the same as the barrel or air will just go around the outside of the dart and not into the silencer.
Ok thanks for the that stuff. I will probably stick with 30-40 psi considering there are some nice houses around where i live and it wouldn't be good to hit them.
Thanks for the information. Im working on a design that delivers slightly more psi. I hoping for around 70 because i will be using an electric pump probably, unless i find a good hand pump to use, but i doubt a hand pump could deliver that psi.
I would also be interested in what pump you used because it would produce the distance i wanted also.
Hey, i was wondering if u have a general plan of your gun that you could post. I would like to see how it is made so i have a better idea of what I need to do to create my own homemade using a hose handle.
