Dart Zone Pro MK2 Air Seal Parts

These are some experimental parts designed for the Dart Zone Pro MK2. 

I noticed that the blaster had a significantly better air seal when the barrel was pushed further back, but this may have been a quality control issue. The ring goes between the front of the metal barrel and the frame, pushing it back towards the pusher my a millimeter or so.

The other issue I noticed was the plunger losing it's air seal due to tilting up and down during firing. The stabilizer should help prevent this. It simply slides onto the back of the plunger rod.
