S200 - no barrel/TP seal?

[pelletcaster]

Hi guys,

here a curious question.
I disassembled my CZ200S-Green and found out that there is NO transfer port seal at all!?
Couldn't believe it and checked diagragram and parts list immediately - so it is. No sign of any seal / O-ring,...

How the hell is this possible?
At the contact point of the transfer port at the receiver to the barrel a good 90 to 130 bar (depending on reg- & thus power-set) are approaching - and no seal?
Or should the barrel to the receiver be sealed with some glue?

Please help - comment, propose ideas.

Thanks a lot.
Andreas

You are right. There is no seal. Just a very good machined fit and sufficient depth of bore. What you need to remember is the high pressure is momentary. I have checked for blow back and didnt find any, the first time inoticed this.
