The Steyr Pro X (52cm barrel)Let's see that airtube and barrel increase 1.5 - 1.75x in length and maybe we've got the makings of a NRL22 gun??
Regarding air - on my Pro X 16J .177 I get around 150shoots from 200-100bar. Steyr are very air efficient - they dont need big air reservoirs. I still dont get how they manage to do it.
