The fastest growth area in paintball at the present time is the conversion of markers from CO2 to compressed air. With this in mind the UKPSF would like to bring to player’s attention the need to have cylinders tested at approved intervals. Testing must be carried out on all full fibre wrap after three years and half fibre wrap bottles after five years from the date of manufacture., Steel and Aluminium bottles must also be tested five years from the manufactured date. This applies to ALL bottles of 0.5litre capacity and above including CO2 bottles.
oops.... that would answer that then
