I wanted to set up my old "backup mag" for my daughter. It shoots beautifully with compressed air. I hooked up a small co2 tank for her and trigger sticks every 2 or 3 shots. It is set up with air in bottom line to expansion chamber to classic valve.
My other mag classic shoots (without an expansion chamber) from the same co2 tank without a problem.
Any ideas to solve while continuing to use co2?
