I have a new LCS-19 in .25. I have attempted to remove the barrel for cleaning. The two screws retaining the barrel are so tight that I have stripped one. So far I have sent 2 emails to LCS for advise and/or repair with no response. Is this how they operate? I am expecting a bit more from a provider of high end airguns. Any advice much appreciated. BTW the phone number goes to a mailbox that is "not set up...good bye".
