It's a solenoid valve alright.

About the foam tip..
There are kinds of foam that are open structured, but also kinds that have a closed cel structure.
The latter will obviously not work.

There is a big chance that regardless of the type of foam, it will get blown to bits.
If you want to have a silencer, than build a proper one.
Like what you mentioned, but inside a container, usually a tube.

Using the absorbing kind of foam ofcourse...

Yippy kai aye mother plucker! :o
That's blurring the line between potato gun and big bore airgun! (...Oh for some way of making rifling! :cry: )
I love it! :P
It looks like you could, (if you feel like it's warranted of course,) move your foresight to the end of the barrel to give a slightly longer sighting radius.
Have you chronographed it at all?
Beautiful, simply beautiful.
