This already looks like an Ion to me.on the Ion the part that would be called the top hat here is called the bolt stop and is held in by the breech and firing can.
Sorry for the size. I can't resize it.
The problem is going to be trying to get the correct Volume and Pressure Air to fire a Ball 300 FPS. If you were to make the dump chamber(or firing chamber) on a matrix or an ion a smaller diameter than you would have to up the pressure or make it longer to compensate. The PMR is basically the design you have but I don't think that Dye wanted to make the PMR Longer to compensate for the smaller Diameter dump chamber.
