I have a rifle Feinwerkbau sport 124- cal 4.5/1.77 for many years. But the front seal of the piston broke and i got a new one original. I istall the new seal properly, but when I shoot more than 10 shots the power goes down.I don´t an some one tell me about this problem. My e mail is firstname.lastname@example.org. I am realu sad beause this is a fantantastic gun.
