My 2025's air chamber is leaking and would like to know if it's an easy fix or if you know who can repair it for me. Thank you for taking the time to reply.

Most likely just need new seals. Search for "reseal Anschutz air rifle cylinder" for parts and the procedure.

If you strike out there then contact any of the typical Anschutz repair resources like Pilk guns, Neil Stepp (ISS), etc.

Good luck.
