+1 to that.
Got to love the Giss system!
The rear piston's momentum just about eliminates the front piston's bounce via the rack and pinion. It also delivers a perfectly timed rearward thump to the cylinder's end-cap to counter act the front piston's forward thump as it hits the bottom of the cylinder.
Brilliant!

A close second would be the Anschutz Mod 220.
Superb modular trigger, self adjusting spring guide, pneumatic recoil damper, two counter-wound springs, fixed barrel, pellet loading aid, can be dismantled using just a screw driver.

What is more impressive is that both were produced in the early 1960's.
