The current fashion would be to button the piston and fit a parachute seal, its interesting to see what was done many years ago when tuning air rifles...have we really improved them, thats what I'd like to know.
Floating as opposed to fixed to the rear block as the original one was. Looking at the slight wear points on the piston I'd say buttoning would have been even better but it's pretty good as is. The transfer port has also been opened up a little. There's virtually no spring preload now and yet power is right up near the limit.
