I've got an Azodin Kaos D that I'm having troubles with. When I go to shoot paint through it the bolt will move forward and then cycle back, but as it cycles back it won't stop shooting air until I turn off the asa. It cycles perfectly normal when firing just air, but I did notice a little blast of air that felt like it was coming out of the back of the bolt. I have gone through and lubed everything, and the striker o-ring is intact. The only thing I can think of it being is the ZeRo System. Has anyone else had a problem similar to mine? Leave anything that you think would help!
