First update to the produced classic Ion conversion kit version. I designed a better way of retaining the rear fitting and the firing piston that has a few advantages.
- The piston is 40% lighter than before
- The chamber is devolumized slightly which helps both efficiency and reducing shootdown at higher rates of fire
- The kit is less obtrusive on the outside of the gun visually
- no more need to remove the back end of the body like when doing a BOB mod, a simple hole for some tubing will suffice for a barbed fitting, smaller cutout for a push to connect elbow
So unless someone is bent on having the version with the extended donut, all subsequent kits will be made with this style back end - the donut and rear plug are no more.
This is the extent of the kit outside of the firing can, except for the fitting.
Original piston on the left, Version 2 on the right.
Piston guide visible inside the can.
The front of the piston guide is hexed so you can install it with a 1/2" nut driver.
Breakdown of the guide. I will be adding an additional air groove and hole in the center piece to aid in maximizing airflow.
Back side of the outer portion of the guide. O-ring seals against the back inside of the can forcing air to move between the 2 pieces that the piston rides in and into the chamber only when the piston is forward.
