Hey shooters!!! Trying to figure this one out . Maybe someone out there can give me a little direction! 1500 rounds in and all is well till last week I pulled the trigger and click! Tank was half full so I drained it with the blender screw and recharged to 3/4 full and same issue. Just no air flow whatsoever! I am reaching out cause hatsan seems to not respond to any customer request forms , emails, or voice messages! I always use double filters when filling tank so I don’t think it’s a moisture issue especially after 8 weeks of use! I feel like it’s a valve issue or something?? Can anyone help?
