I have 700mm classic, but the barrel is solid. Not heavy superior as mentioned.. why is that ?

looks like the liner/barrel is inside the barrel tube. That threaded part in your picture can be unscrewed and the barrel is inside.

pay atention if you remove it as there is a front and rear direction to the liner. One side has a circle a short distance from the end its the breech where the pellet enters the barrel. also just (snug) that piece with the screws when re-assembling it.

Did not remove it.. strugling with valve leak. Lapped the seat,still leak.

I think the puff of air is a Oring in the breech end of the barrel transfer port. two Orings inside the brass part of the barrel. The pellet probe is sealed by those Orings when the gun is fired

Problem was missin the smalla 3.5x1mm o-ring in valve body..
After assembly new problem that air is leaking from barrel, so something with valve or valve body, allready tried lapping valve/valvebody.. need to change all o-rings and test.. or then need a new valvebody/valve rod.
