Kalibrgun Repair Sources or DIY?

Hi - I have a Kalibrgun .22 Cricket 2 Tactical 60. It leaks when I try to fill it.

1) with the diagram from Kalibrgun how much of a job is it to fix it myself?

2) Repair options for shipping it to a shop?

3) Anyone have the specs on the fill probe o-ring?

Thanks for any help....
Leaks from where?
Are you filling from empty or below regulator pressure?
 
Give Charlie a call.
