1/4" anyone have one like this?

Cannons powered by pneumatic pressure (compressed gas) using a valve or other release.

anyone have experience with this qev in 1/4"? I was wondering if it could fill from the chamber side. it would look so much cleaner.

I'm guessing no, but you could modify it to fill from chamber side. Play around with a few springs and the equalization hole until you get it working.

Unmodified you can't. Heat up a needle and poke a tiny hole, add a spring behind the piston and you will be able. However, don't fill it too fast, of course.

No problem.

Poland is right.
On the picture above: the top is the pilot, the side is the chamber and the bottom where it stands on is the barrel.
