This is one maker’s published lineup, not a list of every tank sold. A tank’s volume label is not a shot-count promise. Marker efficiency, operating setup and regulator requirements differ, so do not estimate shots from the bottle size alone.
Before choosing a tank
- Check the marker manual for its approved air source and input requirements.
- Read the bottle’s volume and pressure rating from its label.
- Confirm regulator output, tank thread and marker compatibility with their makers.
- Compare the tank dimensions and weight with the marker and shoulder setup.
- Follow the cylinder inspection, filling and service instructions on the tank.
