Yes Dave. Although no Steyr designer i would have thought that all the air would be used. I'm judging that by the work that has gone into the design/shape of the air chamber.

I am missing the foam spacer in the breech. A shallower replacement has been made and put in place. Would the lack of this part or shallower replacement cause air leakage at this point?
Hi Helen, the foam spacer is there just to stop a pellet falling into the area around the barrel. The barrel to breech seal is purely the breech o ring and the pressure set when locking the cocking lever closed. It's very odd that adjusting the stab would change anything apart from perceived 'kick' on firing.
