I have an older Alpha Black. When the barrel is off the marker it recocks without issue, sounds like it has plenty of power and cyclone advances every time. When I put the barrel on the marker and shoot it does not advance the cyclone and will not recock the marker. This is repeatable every time. I have taken the marker apart and lubed everything I know to. I have replaced the rear bolt o-ring and spring. This marker was not heavily used but did set for ~6 years before trying to get it to work again. Please help trying to get this setup for my daughter to use.
