thanks for the advice guys and lumps no thay dont sell paintball stuff but thay do fill the bottles but thanks guys p.s
do you still have to test them if its a steel tank just that some one told me when i had a co2 tank years ago that you dont this bottle is a back up just incase by the way thanks mike
You cannot continue to use an expired bottle, fibre, aluminium, co2
With the price of aluminiums it can be cheaper to buy new then test (especially if you need to post it)
There is an exclusion for small diameter bottles. I've only seen details to back this up for CO2 in the US. It's been mentioned about 13ci air cylinders now that they are more commonly available here, but mine is marked that it will need testing
